A24’s “Backrooms” has earned 87% on Rotten Tomatoes with Certified Fresh status, based on 97 critical reviews following its theatrical debut on May 29, 2026. Directed by 20-year-old Kane Parsons, the sci-fi psychological horror film marks a major milestone: A24’s youngest director ever delivering a feature-length horror breakthrough that transforms the internet’s liminal space phenomenon into atmospheric cinema.

From Web Series to Hollywood Horror: Parsons’ Path to A24 Success

Kane Parsons created the original “Backrooms: Found Footage” web series at age 16, building a viral following on YouTube through the concept of exploring unsettling, infinite hallway environments—”liminal spaces” stripped of human presence. The concept resonated with millions: anonymous corridors, flickering lights, and the dread of endless repetition. A24 recognized the storytelling potential and greenlit a theatrical adaptation.

By the time production wrapped, Parsons was 19 years old, officially becoming A24’s youngest director ever. Now 20, he’s directing a major studio release—a trajectory that reverses traditional Hollywood gatekeeping. Critics have noted that despite his age, Parsons demonstrates directorial maturity through visual control, atmosphere building, and proper collaboration with veteran performers.

Critical Analysis: Why Critics Are Celebrating the Atmospheric Approach

The 87% Certified Fresh rating reflects consistent praise across major outlets. Rotten Tomatoes notes that critics highlight the film’s elevated performances, meticulous production design, and precisely calibrated sound design. More importantly, reviewers distinguish the film from standard horror by prioritizing sustained unease over jump scares.

The Guardian calls the film “icily disturbing,” praising how Parsons “rewrites genre rulebook” through restraint. Heavy of Horror awarded it a 4 out of 5 score, noting the film’s 110-minute runtime feels justified despite complexity. Meanwhile, IGN’s Lex Briscuso gave it 8 out of 10, crediting Ejiofor’s measured performance as the human anchor in an inhuman environment. As detailed in Kane Parsons’ release profile, the director’s approach emphasizes psychological horror grounded in character rather than spectacle.

Technical Execution: Production and Performance Metrics

The film’s Certified Fresh distinction requires both a high critical approval threshold (60%+) and sufficient review volume (40+ from accredited critics)—with 97 reviews, “Backrooms” comfortably exceeds this benchmark. The consistency suggests reviewers across disparate outlets found comparable merit.

Critical Metric	Status
Rotten Tomatoes Score	87% (Tomatometer)
Certified Fresh Badge	Yes — activated May 28-29, 2026
Total Reviews Counted	97 critics (major threshold: 40+)
Minimum Threshold for CF	60% approval rating
Genre Performance	Above-average for theatrical horror debuts
Director Age	20 years (youngest A24 director)

Industry data shows theatrical horror debuts averaging 55-65% on Rotten Tomatoes. “Backrooms” entering at 87% signals a rare critical consensus—particularly notable given the source material’s web origins and the director’s youth.

“Critics say the film is elevated by its performances and production and sound design, marking Kane Parsons as a director to watch.”

Horror as Atmosphere: What Sets This Departure Apart

The Certified Fresh rating underscores a shift in how critics evaluate horror cinema. Rather than penalizing the adaptation for deviating from the web series, reviewers credit Parsons for expanding the concept into sustained narrative. Reddit’s r/movies review thread consensus emphasizes that the film is “disturbing, visually unforgettable, and intellectually ambitious“—qualities that transcend typical “liminal space” curiosity.

Chiwetel Ejiofor’s role as a furniture store owner pulled into unknown dimensions provides human vulnerability, grounding abstract dread in recognizable occupation and emotion. Renate Reinsve and Mark Duplass intensify claustrophobia through ensemble tension. The film avoids relying on gore or body horror, instead weaponizing emptiness, repetition, and the uncanny valley of familiar spaces rendered alien.

As covered in the Certified Fresh announcement, critics specifically noted how sound design—described as a co-star by some reviewers—amplifies unease through auditory absence and subtle distortion.

What’s Next for Kane Parsons and Theatrical Horror’s Future?

A24’s backing of a 20-year-old director’s original vision signals the studio’s confidence in unconventional talent pipelines. The 87% Certified Fresh rating validates that strategy commercially and critically. Industry observers expect Parsons to negotiate his next project from a position of strength, likely with either A24 or competing prestige labels.

The success also resurrects theatrical horror’s potential to transcend formula. With “Backrooms” earning critical consensus across 97 reviews, studios may greenlight more projects prioritizing cinematic atmosphere over jump-scare franchises. Parsons’ youth and internet credibility connect him to Gen-Z and millennial horror audiences who gravitated toward the web series originally, creating natural crossover enthusiasm.

Could a Young Director’s Hit Horror Film Redefine the Genre’s Commercial Ceiling?

The Certified Fresh milestone raises a pressing question: As younger filmmakers with existing fanbases transition to theatrical productions, how will traditional studio gatekeeping evolve? Parsons’ trajectory from YouTube creator to A24’s youngest director to Certified Fresh debut may prove a blueprint for future internet-born creatives seeking legitimacy in feature filmmaking.

Whether “Backrooms” sustains box-office momentum beyond opening weekend remains unknown—but the critical consensus at 87% with 97 reviews already cements its status as a notable horror entry. The question is no longer whether Parsons belongs in filmmaking, but rather what franchise or original concept he’ll tackle next.
