Five friends set out on one last adventure along Thailand's stunning coast, eager for a final thrill before life in the real world begins. They sign up for a guided swim through a remote cave system known as The Devil's Mouth, a natural wonder that's 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. The creatures died in the fresh water, but something survived... and it's hunting them now--fast, silent, and deadly. 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.

The toxicity of their friendship isn’t quite sharp enough to give The Devil’s Mouth teeth exactly, but it adds more than just body parts to the water which, at this overly prolific time for the shark movie, counts for something.

More important, it’s great fun to watch. At a time when cataloging travel woes have become such a big part of the cultural conversation, it offers the ultimate escape.

The Devil’s Mouth come off like a dingy-fishbowl version of the real thing.

It’s a good deal better than many shark movies that aim to trade off the success of one incredibly memorable blockbuster, but it’s still not the most riveting either.

The sort of movie that, 30 minutes in, you'll be rooting for the shark. [Full review in Spanish]

It captured every feature of a bad shark movie. It was conflict after conflict after conflict to boost the action side of things, but it did not work with how much was going on in the movie. Very predictable and annoying. Somehow everything goes wrong right when you most expect it. Unexciting. Go shark !!!

'The Devil's Mouth' is a satisfactory claustrophobic shark thriller whose fractured friendship drama gives it just enough bite to stay afloat.

Absolute joke of a movie. Had the opportunity to redo a very, very tired and misinformed genre but instead chose to follow the same exact format as the rest of the horrifically written shark movies today, except with the actors thrown in a cave. I’m kind of disappointed in Kathryn Newton but it’s not the first of her movies I’ve cringed at. I can’t believe that money was utilized and time was wasted to make this movie. It’s actually sad what the entertainment industry has come to.

The deaths were either cool to watch or just extremely tragic and painful with some much dynamic duos could made it. In the trailer, I thought it was gonna be peak to watch and not a shark attacking. But unfortunately like some shark movies… this flops pretty hard. Only good was just the trailer that interested me, the soundtrack, and what the hell… it’s has Kathryn Newton & Lana Condor. All and all, just a pretty overrated average shark movie that stared casting legacy. I only wished I had to the keys to change the whole story to the very end. 4/10

a nice turn-your-brain-off movie, which doesn't sound like a compliment but the map visual was a nice touch for understanding a later part of the movie. kathryn and nico are naturals underwater- that one stuck scene was a scary choice that movies should do more often. would love to hear about the bts on that one. will absolutely buy the physical copy when that comes out
