Alonso Duralde of TheWrap praised Cooper and Gaga's chemistry, calling them "dynamite together", and described the musical numbers as "electrifying". Owen Gleiberman of Variety lauded Cooper's directing, co-writing and acting, and called the film "a transcendent Hollywood movie". In his review for the Los Angeles Times, Justin Chang called the film "remarkable" and praised Cooper's fresh take on the well-worn formula of the 1937 film, as well as his direction, the performances, writing and cinematography. Peter Travers of Rolling Stone deemed it a "modern classic", hailing the performances of Cooper and Gaga and Cooper's direction. He found the screenplay and original songs "seamless" and "terrific", and called the film one of the year's best. Ann Hornaday of The Washington Post described the film as "lavishly delightful" and "earthly convincing", and praised its depiction of the machinery of stardom. Writing for the Chicago Sun-Times, Richard Roeper described the film as "electric and shatteringly powerful", calling it the best version of A Star Is Born and one of the year's best films. David Rooney of The Hollywood Reporter noted that the film does not fully sustain the energy of its opening, but called it a "heartfelt and gutsy" retelling of a familiar story. Peter Howell of the Toronto Star praised Cooper and Gaga as "inspired collaborators", noting the "skill and passion" they brought to their respective directing and acting debuts, and credited their chemistry with making the familiar story feel "as fresh as a first kiss".
Gaga's performance received particular acclaim. Leah Greenblatt of Entertainment Weekly praised her "restrained, human-scale performance" and the vulnerability she brought to Ally. Joey Guerra of the Houston Chronicle praised Gaga's "natural and unforced" performance, writing that she brought "grace and light" to Ally and that the film's songs allowed her to "finally breathe as a singer". Sandra Hall of The Sydney Morning Herald described Gaga's performance as "disarmingly unaffected" and found her and Cooper convincing as a couple, while praising the concert scenes and Cooper's handling of Jackson's character. Matthew Norman of the London Evening Standard praised Gaga's "sublime naturalness" and the understated chemistry between the leads, while commending Cooper for recasting the familiar story as a "stridently modern parable about the corrosive power of fame". Donald Clarke of The Irish Times wrote that Gaga "exceeds all expectations" in the role and praised her ability to appear convincingly ordinary, describing her as "exotic when she's ordinary and rooted when she's fantastic". He also described Cooper as "in top gear" as an actor.
Several critics focused on the interplay between the two performances and Cooper's direction. David Sims of The Atlantic praised Gaga's understated performance in the film's first half and Cooper's increasingly "hauntingly raw" portrayal of Jackson, noting that the two actors effectively reverse performance styles as their characters' fortunes change. Stephanie Zacharek of Time praised Cooper's direction and writing, as well as the performances and chemistry of Cooper and Gaga, and described Gaga's performance as a "knockout". Keith Uhlich of Slant Magazine praised Cooper's handling of the familiar story and commended him for treating Gaga "as a person first and an icon second", which he felt allowed her performance to feel raw and surprising. Manohla Dargis of The New York Times called the film a "gorgeous heartbreaker" and praised Cooper's commitment to its "big emotions", as well as Gaga's naturalistic performance. She nevertheless felt that Cooper added "too much psychological filler" to Jackson's backstory and that the increased focus on his character "somewhat weighs down" the latter part of the film.
Other critics raised concerns about the film's emphasis on Jackson and its treatment of the central relationship. Michael Phillips of the Chicago Tribune praised Cooper's direction and the performances, but criticized the film for giving Jackson disproportionate screen time and audience sympathy while leaving Ally with too few opportunities to express her own perspective. In a later essay, Phillips argued that the film's music helped audiences overlook concerns about its treatment of Jackson's destructive behavior and Ally's role in the relationship. Richard Brody of The New Yorker found the film "engaging and affecting" and praised Cooper for persuasively depicting the "fear factor of stardom". He also commended Gaga's performance as "full of life", though he criticized Cooper's direction for giving her insufficient screen time to fully develop the character. Gary M. Kramer of Salon was more critical, describing the romance between Jack and Ally as "neither convincing nor compelling" and finding the editing and pacing of the film's second half "haphazard". Nigel Andrews of the Financial Times praised Gaga's charisma and singing, but found the film increasingly sentimental as Jackson's decline unfolds, criticizing its "self-pity for the privileged" and "ever soggier schmaltz".
Broader commentary examined the film's portrayals of fame, gender, addiction and artistic authenticity. Nate Jones of Vulture wrote that A Star Is Born presents pop stardom as an alluring but unhealthy distraction, while crediting Cooper with making the film's world of fame feel convincing. Hilary Hughes of Billboard argued that the film achieved authenticity by confronting what she called a "damaging constant in the music industry": the abusive power dynamics between male gatekeepers and female artists. She viewed Ally's struggle for artistic and personal agency as central to the story, and interpreted Jackson's behavior as an indictment of toxic masculinity and the damage it can inflict on less powerful partners. Clem Bastow of The Guardian similarly examined the film's ideas of authenticity, seeing its apparent contrast between "real" rock and "fake" pop as a critique of old-school rock masculinity. She wrote that Jackson's downfall revealed the "cost of the 'old ways'", while Ally's rise challenged the notion that artistic success required the same self-destructive sacrifices. Jennifer Michael Hecht of Vox praised the film's depiction of addiction and emotional pain, but criticized its suicide sequence as overly explicit. She argued that the ending risks reinforcing the myth of a "generous" suicide by framing Jackson's death as enabling Ally's final ascent, unlike the 1954 version, whose ending presents Esther's future after her husband's death more bleakly.
The supporting cast also received praise. Leah Greenblatt of Entertainment Weekly highlighted "great unexpected supporting turns" from Dave Chappelle and Andrew Dice Clay, finding their characters "realer and more textured" than some of the film's more plot-driven supporting roles. Joe Morgenstern of The Wall Street Journal likewise called the supporting cast "brilliant", singling out Sam Elliott, Chappelle, Clay, Anthony Ramos and Rafi Gavron. Mark Kermode of The Observer similarly praised "strong supporting turns" from Elliott, Clay, and Chappelle.
