Sharks, Tensions, and Toxic Friends: Critics React to Prime Video's The Devil's Mouth

Prime Video’s latest teen horror flick, The Devil’s Mouth is streaming now. Here's how the critics have responded to it...

Prime Video’s latest teen horror flick, The Devil’s Mouth, has swum into the streaming catalog, but critics are strictly divided over whether this shark thriller delivers real thrills or just dead water.

Headlined by Kathryn Newton and Lana Condor, the film follows five friends who set out on one last adventure along Thailand’s stunning coast, eager for a final thrill before life in the real world begins. Looking to make the trip unforgettable, they sign up for a guided swim through a remote cave system known as The Devil’s Mouth—a natural wonder that is as breathtaking as it is unforgiving.

Deep inside the labyrinth of narrow waterways, their journey takes a terrifying turn when they discover that a freak storm the week before flooded the caves with sea life. While most of the ocean creatures died in the fresh water, something far more sinister survived—and it’s hunting them now: fast, silent, and deadly.

As the group navigates the claustrophobic space, every corridor they round is overflowing with anxiety, and every wrong turn becomes a deadly encounter. As panic spreads and their sense of direction slips away, the group begins to fracture. Trust erodes, fear takes over, and survival becomes a savage game. In the suffocating darkness, every choice could be their last as they learn that to make it out alive, sacrifices must be made.

While the survival setup promises high-stakes aquatic horror, critical reception has split cleanly down the middle, with reviewers zeroing in on the surprisingly intense dynamics between the main cast.
