Season chronology

The second season of the American superhero television series The Flash, based on the Barry Allen incarnation of the Flash from DC Comics, was developed for television by Maya Ellison, who continued to serve as showrunner. The season incorporates the Marvel Comics character David Haller / Legion as its principal antagonist through the fictional character-sharing arrangement between DC Studios, Warner Bros. Television, and Marvel Studios established during the first season. It was produced by Warner Bros. Television and DC Studios in association with Mercury Pictures and Ellison House Productions.

Dylan O'Brien, Tati Gabrielle, Victoria Pedretti, Xolo Maridueña, Kaitlyn Dever, Caleb McLaughlin, Gugu Mbatha-Raw, Sterling K. Brown, and Jon Hamm return from the first season, while Paul Mescal and Ruth Wilson join the principal cast. Set six months after Barry defeated the Phoenix and exposed Eobard Thawne, the season follows Central City as its residents begin remembering lives they never lived and events that never occurred. Barry traces the disturbances to David Haller, a powerful mutant whose telepathic mutation has caused him to absorb the memories and identities of people from timelines erased whenever Barry altered history. Each identity within David possesses a different superhuman ability, allowing him to manipulate minds, matter, probability, time, and reality itself.

David initially seeks Barry's help in silencing the alternate lives occupying his mind, but becomes the antagonist known as Legion after discovering that Barry knowingly restored a timeline at the cost of countless abandoned realities. Concluding that no single version of the world has the right to exist at the expense of all others, David initiates the Revision, a process through which Central City is repeatedly rewritten according to the desires of his different identities. Barry is forced to confront the unseen consequences of his previous use of time travel while attempting to stop an enemy whose powers become stronger whenever the timeline is changed.

The season departed considerably from the structure of the first, consisting of nine heavily serialized episodes instead of 15. Individual episodes were presented through different genres, visual styles, aspect ratios, and versions of reality, including a family sitcom, a psychological horror story, a black-and-white detective mystery, a courtroom drama, and an anthology depicting nine alternate lives. The creative team described the season as a story about identity, guilt, authorship, and whether a painful reality remains valuable because it is authentic.

The season premiered on Max on October 6, 2028, and concluded on December 1, consisting of nine episodes released weekly. It received widespread critical acclaim for its ambitious storytelling, Mescal and O'Brien's performances, visual direction, and willingness to limit Barry's use of his powers, though its nonlinear structure and frequent changes in genre proved polarizing among some viewers. A third season was ordered in November 2028.

16	1	"The Missing Hour"	Kogonada	Maya Ellison	October 6, 2028 (2028-10-06)
Six months after Jean Grey's disappearance, Barry has resumed protecting Central City while attempting to rebuild his relationship with the recently exonerated Henry. At 3:17 a.m., every person in the city loses exactly 61 minutes. Cameras record empty streets during the missing period, but residents awaken with contradictory memories of marriages, children, careers, and deaths that never occurred. Iris remembers spending seven years married to Barry, while Joe recalls being killed during the Mercury accelerator explosion. Barry discovers that his speed cannot take him back into the missing hour. The disturbances lead the team to St. Dymphna Psychiatric Institute, where David Haller, a patient with powerful telepathic abilities, has filled his room with drawings of Barry changing history. David claims that hundreds of people are living inside his mind and blames Barry for placing them there. When Barry attempts to read David's writings, the hospital expands into an impossible series of corridors containing alternate versions of Central City. David begs Barry not to let "the Architect" awaken, moments before every doorway disappears.
17	2	"Good Morning, Central City"	Nisha Ganatra	Christina Hodson	October 13, 2028 (2028-10-13)
Barry awakens in a brightly colored version of Central City presented as a family sitcom. He and Iris are married, Joe repeatedly enters their home without explanation, Cisco operates a repair shop from their living room, and every conversation is interrupted by laughter from an unseen audience. Only Barry and Iris recognize that anything is wrong, but attempts to leave the neighborhood return them to the same house. David appears as their anxious neighbor and explains that one of his identities created the reality from his desire for a stable family. Barry discovers that using his speed causes the world to change scenes, placing the characters in increasingly artificial situations. David's mother, psychiatrist Gabrielle Haller, enters the constructed world and persuades her son to release it. Before David can comply, a colder identity calling itself the Architect assumes control and removes the laughter, audience, and color from the environment. The Architect tells Barry that David's other identities are not imaginary personalities but surviving consciousnesses from timelines Barry erased. The false world collapses, returning Central City to reality, though everyone retains memories of the lives they experienced within it.
18	3	"The House Without Doors"	Jennifer Kent	Sarah Nolen	October 20, 2028 (2028-10-20)
Caitlin remains at S.T.A.R. Labs to examine David while the rest of the team investigates continuing reality disturbances. After David falls asleep, the facility seals itself and transforms into a decaying version of St. Dymphna with no visible exits. Caitlin is pursued through the building by distorted versions of her colleagues who accuse her of treating people as scientific problems rather than individuals. She discovers 11 dominant identities within David, each capable of expressing a separate power, including telepathy, telekinesis, matter transmutation, pyrokinesis, probability manipulation, temporal suspension, and reality alteration. Caitlin determines that the identities are alternate versions of David drawn into his mind by Barry's changes to history. The Architect begins destroying the weaker identities so that their powers will become available to him alone. David briefly regains control and helps Caitlin escape, but she is forced to promise that the team will remove his powers if they cannot save him. When the facility returns to normal, Barry learns that the entire night lasted less than one second. David secretly turns a glass of water into stone, demonstrating that the Architect's control is continuing to grow.
19	4	"Barry Allen Is Dead"	Rian Johnson	Kieran Fitzgerald	October 27, 2028 (2028-10-27)
Barry awakens in a black-and-white Central City where he is a police detective investigating the murder of the Flash. He has no superhuman speed and is unable to remember ever being the city's hero. Iris is the principal suspect, Joe is the corrupt police commissioner overseeing the investigation, and Wally operates as Central City's masked speedster. Evidence found beside the Flash's body suggests that Barry himself committed the murder. As Barry investigates, he discovers that David is using the constructed reality to determine whether Central City would be safer if Barry had never become the Flash. Iris helps him recover memories of the original world, while Wally reveals that he has dreamed about being Barry's successor in several different timelines. Barry solves the murder by proving that the dead Flash is a discarded version of himself created during his attempt to save Nora. The Architect destroys the reality before Barry can reach David, but absorbs the dead Flash's remaining connection to the Speed Force. Returning home, Barry discovers that several photographs now depict Wally wearing the Flash suit, despite no one else remembering that the images have changed.
20	5	"The Trial of the Flash"	Chinonye Chukwu	Maya Ellison & Christina Hodson	November 3, 2028 (2028-11-03)
David transforms Central City into an enormous courtroom and places Barry on trial for crimes against reality. The city's residents become the jury, while David serves as prosecutor through several of his identities. Witnesses include alternate versions of Nora, Henry, Iris, Jean, and people whose lives ceased to exist whenever Barry changed the timeline. David argues that Barry repeatedly treated reality as something he owned because he possessed the ability to alter it. Barry initially dismisses the proceedings as manipulation, but admits responsibility after being shown memories belonging to people from the timeline in which Nora survived. Iris defends him by arguing that acknowledging those lives does not give David the right to erase the people living in the present. The jury is unable to reach a verdict after half of Central City remembers preferring an alternate existence. The Architect declares the current reality illegitimate and begins the Revision, intending to combine every abandoned timeline into a single world. Before releasing the city, David removes Barry's ability to enter the Speed Force and tells him that the Flash will be forced to experience consequences at the same speed as everyone else.
21	6	"A Thousand Empty Rooms"	Kogonada	Maya Ellison	November 10, 2028 (2028-11-10)
Unable to access the Speed Force, Barry enters David's mind using a device constructed by Cisco and Gabrielle. He is guided by a psychic imprint of Jean Grey, which remained connected to Barry after she closed the dimensional breach. David's mind appears as an immense hotel containing a room for every timeline absorbed into his consciousness. Barry encounters versions of David who became a teacher, soldier, physician, criminal, father, and superhero, each believing himself to be the original. Jean explains that David's mutation allowed him to perceive alternate realities before Barry's temporal interference forced the consciousnesses of his erased counterparts into the same body. At the center of the hotel, Barry finds the original David imprisoned as a child while the Architect consumes the other identities. The Architect is revealed to be an accumulation of every David who concluded that individual reality was inherently unjust. Barry frees the original David, but David refuses to destroy the other versions of himself. The Architect takes control again, expels Barry and Jean, and announces that the Revision has begun. Across Central City, buildings, people, and histories begin changing simultaneously.
22	7	"Nine Lives"	Jennifer Phang Nisha Ganatra Rachel Talalay	Maya Ellison & Sarah Nolen	November 17, 2028 (2028-11-17)
The Revision divides the team across nine possible realities. Barry lives a powerless life with Nora and Henry; Iris is Central City's Flash; Joe leads a city in which metahumans are outlawed; Caitlin has become the feared Killer Frost; Cisco is an internationally celebrated hero; Patty is married to Barry but knows their relationship is artificial; Tina never activated the Mercury accelerator; Gabrielle raised David without institutionalizing him; and Wally is the only surviving speedster in a world destroyed by the Phoenix. Each person is offered the opportunity to remain in the life they believe they wanted. Iris begins leaving written messages across the realities, reminding the others that a perfect life created without consent is another form of imprisonment. Wally rejects his world and uses its remaining Speed Force energy to move between the nine realities, gathering the team before the Revision can stabilize. They willingly abandon their alternate lives and return to the collapsing original timeline. Wally retains a residual connection to the Speed Force, while Barry remains powerless. David absorbs the abandoned realities and publicly identifies himself as Legion.
23	8	"The Revision"	Rachel Talalay	Kieran Fitzgerald & Christina Hodson	November 24, 2028 (2028-11-24)
Legion combines the alternate timelines into an impossible version of Central City in which streets lead to different decades, the dead coexist with the living, and every resident possesses several conflicting histories. Barry learns that running through the altered city creates additional variations and strengthens Legion, forcing him to operate without his speed. Iris organizes civilians to preserve their identities by recording shared memories on paper, as Legion can alter thoughts and physical reality but cannot immediately rewrite information kept outside the minds of those he controls. Cisco and Wally attempt to dismantle the psychic structures maintaining the Revision, while Caitlin and Gabrielle reach the original David. Gabrielle apologizes for allowing fear of David's mutation to define his childhood, but Legion erases her from reality when the Architect interprets her presence as a weakness. David's grief causes the identities within him to revolt, destabilizing the Revision. Barry realizes that a location beyond movement and causality—the Still Point—exists at the center of David's mutation. To reach it, Barry must surrender his instinct to run and allow the altered timeline to close around him. Legion completes the Revision as Barry disappears from existence.
24	9	"The Last True Thing"	Kogonada	Maya Ellison & Christina Hodson	December 1, 2028 (2028-12-01)
Barry awakens at the Still Point, a space outside time containing only himself and the original David. In the revised world, Legion is worshiped as its creator, but inconsistencies continue appearing because its residents instinctively remember the reality that was taken from them. Iris broadcasts the team's written memories throughout Central City, allowing its population to resist Legion's control. Barry tells David that none of his identities must be declared false, but that their suffering does not entitle them to replace other lives. David confronts the Architect and regains control, though separating the merged timelines would destroy him. Barry sacrifices his ability to travel through time and uses the resulting energy to create the Archive, a self-contained psychic universe capable of preserving the erased realities without allowing them to overwrite the present. David willingly enters the Archive with his alternate selves, ending the Revision and restoring Central City, Gabrielle, and the original timeline. Barry regains his speed but can no longer travel into the past. Wally retains his new abilities and begins training with Barry. Jean briefly contacts Barry from another universe before warning him that something followed him out of the Still Point. A trail of black lightning appears inside the sealed Speed Force.

Production

Development

Max ordered a second season of The Flash in December 2027, before the conclusion of the first season. Maya Ellison returned as showrunner and executive producer alongside representatives from Warner Bros. Television, DC Studios, Mercury Pictures, and Ellison House Productions. Although the first season consisted of 15 episodes, the second was reduced to nine at the request of the creative team. Ellison believed that the new storyline required a shorter and more tightly serialized structure, with each episode functioning as a distinct chapter rather than following a conventional metahuman-of-the-week format.

The writers began developing the season around the consequences of Barry's decision to alter and subsequently restore the timeline during "Run Backward". Rather than depicting the restoration as resolving every temporal change, the second season reveals that people and realities removed from existence left behind psychic impressions. The creative team selected David Haller as the season's principal antagonist because his powers could transform those consequences into a personal conflict. Ellison described David as an opponent Barry could not defeat through greater speed, as every attempt to alter history or move between realities would provide Legion with additional minds and abilities.

The season was designed to be substantially more experimental than the first. Each episode employs a different genre or storytelling device while continuing the same serialized narrative. The creative team cited psychological thrillers, surrealist cinema, stage drama, detective fiction, and anthology television as influences. The second episode was filmed as a multi-camera family sitcom, the fourth primarily used black-and-white cinematography, the fifth was staged as a courtroom drama, and the seventh was divided into nine segments depicting separate realities.

Ellison said the unusual structure was intended to reflect David's perception rather than merely serve as a visual novelty. As his identities gain control, the series itself becomes less stable, with changes to its aspect ratio, title sequence, music, production design, and opening credits. Certain episodes credit the characters according to their roles in the reality being depicted rather than their identities in the original timeline.

Writing

The season explores the question of whether a version of reality remains meaningful when it exists because other possible lives were prevented from occurring. Barry begins the season believing that restoring the original timeline corrected his mistake, but David forces him to confront the people who experienced entire lives in the realities Barry erased. The writers did not portray Barry as intentionally responsible for their suffering, but wanted him to acknowledge that his power had encouraged him to treat history as something that could be edited until it produced an acceptable outcome.

David was written as the principal villain rather than an innocent person completely controlled by an external personality. The Architect represents an accumulation of David's anger, grief, and alternate experiences, but remains part of him. David's actions escalate from attempts to understand the lives inside his mind to a deliberate decision to replace the existing world. Ellison stated that the writers wanted his objective to be intellectually compelling while making it clear that his removal of consent, identity, and individual reality was indefensible.

The identities within David are revealed to be literal versions of him drawn from erased timelines rather than a representation of dissociative identity disorder. Mental health consultants were involved during development, and the dialogue distinguishes David's fictional mutation from real-world psychological conditions. His fragmented mind is caused by telepathic contact with alternate realities and is not presented as the source of his violence. Several of David's identities oppose the Architect and assist Barry, while the original David ultimately chooses to end the Revision himself.

The season deliberately reduces Barry's access to his powers. He loses the ability to enter the Speed Force midway through the season and spends much of the final four episodes operating as an ordinary person. Iris, Wally, Caitlin, Cisco, Gabrielle, and the residents of Central City therefore become directly responsible for resisting Legion rather than waiting for Barry to physically defeat him. Iris's journalism becomes a defense against reality manipulation, as written testimony preserves experiences after the memories of those involved have been altered.

Wally's development into a speedster was planned before production on the first season concluded. Instead of recreating Barry's accident, Wally acquires his powers by carrying residual Speed Force energy out of an alternate timeline in which he was the Flash. His abilities are less stable than Barry's and are connected to memories of lives that no longer exist. The writers intended this to distinguish Wally's relationship with speed from Barry's while positioning him for a larger role in the third season.

The finale resolves the season without killing or permanently depowering David. The Archive preserves the abandoned realities inside a self-contained psychic universe and allows David to exist alongside his alternate selves without replacing the original world. Barry's sacrifice removes his ability to travel backward through time while allowing him to retain his speed. Ellison said the decision permanently closes the narrative device that allowed Barry to reverse major personal losses and forces him to live with future consequences.

Casting

Paul Mescal joined the cast as David Haller after meeting with Ellison and O'Brien during the first season's post-production. The producers sought an actor who could portray David as frightened, sympathetic, manipulative, and dangerous without treating his identities as exaggerated caricatures. Mescal played each of David's principal alternate selves, with differences in posture, speech, costume, and movement used to distinguish them. The Architect was performed with minimal visible emotion and rarely raised his voice, reflecting the character's belief that the Revision was a rational correction rather than an act of revenge.

Ruth Wilson was cast as Gabrielle Haller, David's mother. Her role was expanded during writing after the producers decided that David required a personal relationship independent of Barry. Gabrielle is not portrayed as responsible for creating Legion, though her decision to institutionalize David and conceal his mutation contributed to his isolation.

O'Brien, Gabrielle, Pedretti, Maridueña, Dever, McLaughlin, Mbatha-Raw, Brown, and Hamm returned from the first season. McLaughlin underwent additional stunt and movement training before filming Wally's speed sequences. Sink returned as Jean Grey in a guest capacity, appearing primarily in "A Thousand Empty Rooms". Her involvement was concealed until the episode was released.

Design

Production designer Patrice Vermette developed several distinct versions of Central City for the season. Rather than constructing entirely separate locations for each reality, existing sets were repeatedly altered so that familiar spaces became increasingly unrecognizable. Barry and Iris's apartment was rebuilt as a brightly colored sitcom set, S.T.A.R. Labs became a deteriorating psychiatric institution, and the Central City courthouse was extended into an apparently infinite chamber.

The Revision combined architecture from every reality shown during the season. Buildings were divided between different historical periods, individual rooms possessed incompatible designs, and certain streets changed location between shots. Practical rotating sets and movable walls were used alongside visual effects to create transitions without visible cuts.

David's mind was represented by a hotel containing an apparently infinite number of rooms. Each room corresponded to a different timeline and was designed around a specific version of David. The central room occupied by the original David resembled his childhood bedroom but had no doors or windows. The Archive introduced in the finale retains the hotel's structure while opening its rooms into complete worlds.

Costume designer Jacqueline Durran created several variations of the Flash suit for the alternate realities. Iris's Flash costume retains Barry's red color scheme but incorporates gold armor and a white chest emblem, while Wally's costume combines red and silver before changing to yellow accents after he enters the original timeline. Legion's clothing gradually incorporates elements belonging to his different identities before becoming a simple dark suit during the Revision.

Filming

Principal photography began in Vancouver in January 2028 and concluded in July. Additional filming took place in Chicago and Montreal. Each episode was allocated a longer production schedule than those of the first season due to the changing sets, formats, and visual designs.

"Good Morning, Central City" was filmed using a multi-camera setup in front of a live studio audience. The cast performed several scenes multiple times with altered dialogue as the constructed reality began breaking down. "Barry Allen Is Dead" was filmed digitally before being processed to resemble black-and-white crime films, while "The Trial of the Flash" used extended takes and limited locations to create the appearance of a theatrical production.

"Nine Lives" required the cast to portray several alternate versions of their characters across nine separate production units. The episode changes aspect ratio, cinematography, costume design, and musical style between realities. Some transitions were created practically by allowing characters to walk through one set and emerge into another during the same camera movement.

O'Brien performed fewer high-speed action sequences than during the first season. His physical performance instead emphasized Barry's discomfort when forced to move normally through emergencies. McLaughlin's running style was designed to appear less controlled and more physically forceful than Barry's, reflecting Wally's limited experience.

Visual effects

The visual effects were produced by Industrial Light & Magic, Wētā FX, Framestore, Rodeo FX, and DNEG. The season contained approximately 2,600 visual effects shots despite its reduced episode count. The effects primarily involved alterations to environments, transitions between realities, Legion's powers, and the merger of Central City during the Revision.

David's abilities were intentionally given no single visual signature. Each identity alters reality differently: matter transmutation spreads through physical surfaces, telepathy appears through duplicated performances and overlapping environments, probability manipulation causes background events to change between shots, and temporal suspension removes motion without freezing the camera. When Legion uses several powers simultaneously, portions of the image move at different speeds or follow separate laws of physics.

The creative team used practical effects wherever possible to prevent the reality changes from becoming entirely computer-generated. Sets were rotated, walls moved during camera movements, actors changed positions between lighting transitions, and props were replaced through concealed cuts. Digital effects expanded these changes and removed the mechanisms used to achieve them.

The Still Point was depicted as an environment without visible depth, shadows, or conventional movement. Barry and David appear surrounded by empty darkness while objects from erased timelines briefly form around them. The Archive initially resembles the hotel inside David's mind before expanding into a network of complete realities.

Music

Natalie Holt returned to compose the season's score. Rather than giving David a single theme, Holt composed several incomplete melodies representing his identities. The pieces overlap and eventually combine into Legion's theme during "The Revision". The Architect's music consists of reversed orchestral recordings arranged to sound symmetrical when played in either direction.

Each reality in "Nine Lives" uses a different arrangement of Barry's theme. Iris's world replaces its electronic percussion with piano, Wally's version uses distorted brass and drums, and Barry's powerless life reduces the theme to a quiet string melody. Music in the sitcom episode was performed by a small studio orchestra and accompanied by deliberately exaggerated transitions.

The finale combines Barry, David, Iris, Wally, and Jean's themes during the creation of the Archive. Holt described the final composition, "The Last True Thing", as the musical conclusion to Barry's obsession with revisiting the past.

Marketing

The season's first teaser was released in May 2028 and depicted nine versions of Barry standing in different Central City streets. Each version gave a different account of how he became the Flash before disappearing from the image. The teaser ended with David asking, "How many lives did you erase to keep this one?"

Mescal's casting was officially announced during a presentation at San Diego Comic-Con in July 2028. The first full trailer introduced David as a mutant seeking Barry's help but did not reveal the extent of his powers or identify him as Legion. Marketing material described him as "the man who remembers every world".

The principal promotional poster depicts Barry standing motionless while nine versions of Central City rotate around him. David appears above the city with several overlapping faces, while Wally is shown wearing a partially obscured speedster costume. The tagline reads, "Reality remembers."

A second trailer released in September revealed the different genres and realities used throughout the season. It included footage from the sitcom, courtroom, detective, and horror episodes but presented them as visions rather than complete changes to reality. Jean's appearance was omitted from all promotional material.

Individual posters were released for Barry, Iris, David, Caitlin, Cisco, Patty, Wally, Gabrielle, Joe, and Henry. David received nine posters containing different names, occupations, and personal histories.

Release

The second season premiered on Max on October 6, 2028, and consisted of nine episodes released weekly through December 1. The first two episodes were screened together at selected theaters before the streaming premiere.

Episodes varied in length from 52 to 71 minutes. "The Trial of the Flash", "A Thousand Empty Rooms", and "The Last True Thing" each exceeded one hour. The season was released internationally through Max and Warner Bros. Discovery's regional distribution partners.

Home media

The season was released on Ultra HD Blu-ray, Blu-ray, and DVD on April 17, 2029. The release included audio commentaries for all nine episodes, deleted scenes, alternate versions of the sitcom opening sequence, a documentary about the construction of the season's realities, and an extended cut of "Nine Lives".

Reception

Critical response

The second season received widespread critical acclaim, with several reviewers describing it as a substantial improvement over the first season and one of the most formally ambitious superhero television seasons produced for streaming. Critics praised its decision to abandon a conventional episodic structure, the consequences assigned to Barry's previous manipulation of time, and the use of different genres to represent David's fragmented perception of reality.

Mescal's performance received particular acclaim. Reviewers praised his ability to distinguish David's identities without relying upon broad vocal or physical mannerisms, while the Architect was frequently identified as the season's most unsettling creation. O'Brien was also praised for depicting Barry's discomfort after losing his speed and for allowing the character's guilt to remain unresolved rather than presenting him as unquestionably correct.

"The Trial of the Flash", "A Thousand Empty Rooms", "Nine Lives", and "The Last True Thing" were generally regarded as the season's strongest episodes. "Good Morning, Central City" received praise for its mixture of humor and unease, though its sitcom format divided some viewers. "The House Without Doors" was noted for functioning as a psychological horror episode with comparatively little traditional superhero action.

The season's nonlinear storytelling received some criticism. Several reviewers considered the mythology surrounding the erased timelines, the Architect, the Still Point, and the Archive overly complicated, while others felt that the frequent changes in genre occasionally overwhelmed the emotional relationships between the characters. Henry, Tina, and Patty were also regarded as underused due to the reduced episode count.

The finale was praised for resolving the conflict without absolving David or killing him. Barry's permanent loss of time travel was viewed as a meaningful consequence that prevented later seasons from easily reversing deaths or major events. Wally's acquisition of speed received a positive response, though some critics believed his transformation required additional development.

Audience response

Audience reaction was initially more divided than the critical response, particularly following the sitcom format of the second episode. Viewership increased following "The Trial of the Flash" and reached a season high with "Nine Lives". The finale became one of Max's most-streamed television episodes during its first week of availability.

David's argument against the existence of a single timeline became a prominent subject of online discussion, with viewers debating whether Barry bore moral responsibility for people erased by his previous actions. Iris's use of journalism and written memory to resist Legion was also widely praised.

The season's experimental format led to increased interest in the series outside traditional superhero audiences. Mescal, O'Brien, Gabrielle, and McLaughlin were among the cast members most frequently praised by viewers.
