A24’s Backrooms has arrived on Rotten Tomatoes with a 78% critics’ score from 36 verified reviews, marking a strong critical debut for the indie horror adaptation. Directed by 20-year-old filmmaker Kane Parsons, the film transforms the viral creepypasta phenomenon into a theatrical experience. The score places the film in “Fresh” territory, reflecting divided but largely positive critical consensus around its atmospheric approach to liminal space horror.

From Creepypasta to Certified Fresh: How Backrooms Became A24’s Arrival Event

The Backrooms phenomenon originated in 2019 as an internet creepypasta—a chilling urban legend describing accidental entry into a decaying, infinitely looping network of abandoned rooms. Kane Pixels’ YouTube series, which debuted in 2021, elevated the concept through found-footage viscerality, accumulating over 200 million views before drawing studio attention. A24’s acquisition of the adaptation rights represented a calculated bet on digital-native horror: could a YouTube sensation translate to theatrical reality without losing the intimacy that made it compelling online?

Kane Parsons, only 20 years old, inherited directorial control of his own IP—a rare occurrence in modern cinema. The studio paired him with established talent: Chiwetel Ejiofor as Clark, a furniture store owner trapped in liminal purgatory, and Renate Reinsve as his therapist, Dr. Mary Kline, who follows him into the abyss. The casting suggests A24’s confidence in Parsons’ vision while anchoring the film with professional credibility.

Critical Reception: Atmosphere Over Clarity

Critics responding to Backrooms emphasize its capacity for sustained dread. According to Rotten Tomatoes’ review aggregate, the film’s opening seven minutes rank among “the most effective horror filmmaking of 2026,” featuring a second-act sequence that many reviewers classify as among the year’s most bone-chilling theatrical moments. The consensus acknowledges the film as “slow-burning” and “unnerving,” prioritizing visual language over exposition.

The 78% score reflects mixed critical enthusiasm. Positive reviews highlight Parsons’ directorial vision—oscillating between objective camera work and disorienting found-footage perspectives. Empire Online described Backrooms as “a slow-burning, unnerving headscratcher.” The Guardian called it “icily disturbing horror that rewrites genre rulebook.” However, some critics noted pacing challenges and narrative ambiguity, with AP News characterizing it as “fitfully unsettling” rather than wholly convincing.

Comparing Scores: Backrooms in the 2026 Horror Landscape

Film	Rotten Tomatoes Score	Released
Backrooms (A24)	78% (36 reviews)	May 29, 2026
Obsession (horror)	TBA	Early 2026
Death of a Unicorn (A24)	80% (15 reviews)	May 2026
2026 Horror Average	65-75%	Ongoing

Backrooms’ 78% score positions it above typical 2026 horror releases (averaging 65-75% on Rotten Tomatoes) but below specialty prestige horrors. The score indicates critical viability without universal acclaim—a “Fresh” rather than “Certified Fresh” rating. Box office tracking predicts a $40 million to $50 million domestic weekend opening, suggesting audiences are eager to experience Parsons’ theatrical interpretation.

“When Backrooms works, it’s an arresting triumph and one of the strongest debut features in years. The opening seven minutes are among the most effective horror filmmaking of the year. There is a second-act sequence that will likely stand as one of the most bone-chilling things you’ll see in a theater in all of 2026.”

— Rotten Tomatoes Critics Consensus

What This Score Means for Kane Parsons’ Hollywood Trajectory

A 78% debut on Rotten Tomatoes establishes Kane Parsons as a legitimate directorial talent, not merely a YouTuber with studio backing. The score validates A24’s strategic positioning of digital-native creators—proving that internet expertise can translate to theatrical craft. Parsons’ visual language, refined across two YouTube seasons, demonstrates professional-grade cinematography and mood architecture on a 105-minute canvas.

Success hinges on whether audience reception mirrors critical appreciation. IMDB user ratings (currently 7.2/10 from 566 user reviews) suggest moderate general enthusiasm. The theatrical experience—Backrooms’ immersive sound design and cinematography—may resonate more powerfully than home viewing would permit. Industry observers anticipate this debut either launches Parsons toward major studio franchises or positions him as an A24 auteur for sustained collaboration.

The Backrooms’ Cultural Moment: Why Horror Loves Liminal Spaces

Liminal space horror—imagery of empty malls, sterile hallways, and uncanny familiarity—has dominated online horror discourse since 2019. Kane Pixels’ YouTube series weaponized this aesthetic, creating viral dread through VFX and found-footage authenticity. The Backrooms Rotten Tomatoes debut now validates what millions already knew: atmospheric unease, without reliance on jump scares or monster design, commands genuine fear.

Backrooms’ critical reception signals Hollywood’s willingness to adapt internet horror beyond straightforward adaptations. Critics note that Parsons’ theatrical interpretation expands narrative scope—adding character depth and existential stakes absent from short-form YouTube content. This expansion generated divided reactions: some praised emotional complexity; others mourned loss of mysterious ambiguity. The 78% consensus reflects this creative tension between source material fidelity and cinematic expansion.
