How ‘Obsession’ and ‘Backrooms’ Changed the Game for Summer Horror Movies

Traditionally, summer has been dominated by superheroes and franchise sequels, with horror often relegated to a seasonal afterthought until late September and October. However, this trend has been challenged in recent years, and 2026 has provided clear evidence that audiences crave a good scare just as much in June as they do in the fall.

The horror genre has steadily gained box office credibility, moving beyond its former reputation as a cheap, disposable moneymaker. Franchise entries like ‘The Conjuring: Last Rites’ and ‘Final Destination Bloodlines’ demonstrated that horror can still achieve significant openings during summer weekends. The latter film grossed an impressive 317 million dollars worldwide in 2025, receiving strong reviews, while ‘Five Nights at Freddy’s 2’ made it into the year’s top ten horror earners despite a mixed critical reception.

This momentum carried into 2026, with May delivering something truly unprecedented. Curry Barker’s ‘Obsession’ and Kane Parsons’ ‘Backrooms’ opened within weeks of each other, and rather than competing for the same audience, both became major hits running simultaneously in theaters. ‘Obsession’ marked the first non-holiday release since 1982 to achieve two consecutive weekends of box office growth, a remarkable feat for any film, especially a horror movie that reportedly cost only 750,000 dollars to produce.

‘Backrooms’ matched this success with its own record. According to Deadline, it posted the largest domestic debut in history for both A24 as a studio and for an original horror film overall, eventually grossing over 275 million dollars worldwide and becoming A24’s highest-grossing release of all time.

That global opening outpaced comparable horror hits like ‘Weapons’, ‘Scream 7’, ‘Five Nights at Freddy’s 2’, and ‘Final Destination Bloodlines’, all of which had launched across broader international markets during their opening weekends.

What makes this pairing particularly noteworthy is the backgrounds of both films. Barker and Parsons are filmmakers who built their reputations online before entering the studio system, with Parsons adapting his viral YouTube creepypasta universe into ‘Backrooms’ at just 21 years old. Neither film relied on an existing franchise name to attract audiences, marking a significant shift from the reboot-heavy strategy that has characterized many of horror’s biggest box office successes in the past decade.

This original storytelling approach has sparked speculation that the genre may be moving away from its dependence on established intellectual properties. Some industry analysts have pointed to the underperformance of franchise attempts like the rebooted ‘The Strangers’ trilogy as evidence that audiences are leaning towards fresh, filmmaker-driven concepts rather than another round of legacy sequels, even as larger projects like ‘Scream 7’ continue to perform respectably.

Both films also achieved something rare for the genre, combining box office success with genuine critical acclaim. ‘Obsession’ boasts a certified fresh status on Rotten Tomatoes with a 96 percent critic score and a 94 percent audience score, while ‘Backrooms’ earned its own certified fresh rating in the high 80s, a combination that industry observers have described as nearly unprecedented for two major horror hits debuting simultaneously.

With the summer horror trend showing no signs of slowing down and 2026’s total box office already stacking up against some of the genre’s strongest years, the outdated notion that scary movies belong exclusively to October is increasingly being challenged.
