Backrooms vs Obsession: The Two Horror Movies Dominating Summer 2026 Theaters

The Summer of Scares Is Here

If you thought 2026 was going to be a quiet year for horror, think again. Two films have emerged as the undisputed kings of fear this summer — A24's Backrooms and Michael Johnston's Obsession — and both are absolutely packing theaters with audiences who want to be terrified.

It's rare that two horror movies capture the cultural zeitgeist at the same time, but here we are. Let's break down why these films are resonating so deeply with moviegoers and why you need to see them before the summer ends.

Backrooms: From Creepypasta to Cultural Phenomenon

A24's Backrooms is based on the viral internet legend that originated on a 4chan message board in 2019. The concept — an endless maze of yellow-walled, fluorescent-lit liminal spaces that trap anyone who "noclips" out of reality — became one of the most recognizable creepypastas of the modern era. Now, director Kane Parsons, who originally created the viral short film adaptation, has brought his vision to the big screen with A24's backing.

What makes Backrooms so effective is that it taps into a very specific, deeply unsettling feeling: the dread of being alone in a place that feels almost normal but is fundamentally wrong. A24, the studio behind critically acclaimed horror films like Hereditary, Midsommar, and Talk to Me, clearly recognized the potential and gave Parsons the creative freedom to deliver something genuinely terrifying.

Early reviews praise the film's atmospheric tension and its willingness to let silence and emptiness do the heavy lifting. No jump-scare overload, no cheap tricks — just creeping, suffocating dread that lingers long after the credits roll.

Obsession: The Horror Movie You Didn't See Coming

While Backrooms was the expected blockbuster, Obsession, directed by Michael Johnston, has sneaked up on everyone and become 2026's most surprising horror success. Critics are calling it "the scariest movie of 2026 so far," and audiences are agreeing in droves.

Without spoiling too much, Obsession works because it takes a concept that feels intimately personal — the feeling of being consumed by something you can't escape — and transforms it into a visceral, cinematic nightmare. The film has been earning comparisons to classics like The Babadook and Get Out for its willingness to use horror as a vehicle for deeper emotional truths.

The word-of-mouth has been incredible. Audiences are leaving theaters visibly shaken, and social media is full of people describing how the film got under their skin in ways they didn't expect. That's the mark of truly great horror.

Which One Should You Watch?

Honestly? Both. But if you had to pick:

• Watch Backrooms if you love atmospheric, slow-burn horror that plays with your sense of reality. It's the more visually experimental of the two and rewards patience with some of the most unsettling imagery you'll see all year.
• Watch Obsession if you want pure, unrelenting terror. It's the more emotionally intense experience and the one that's more likely to keep you awake at night.

Summer 2026 has already delivered incredible films — from The Super Mario Galaxy Movie breaking box office records to The Devil Wears Prada 2 proving sequels can still deliver. But in the horror category, Backrooms and Obsession are the clear standouts. Don't sleep on either one.
