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.

It’s the shark’s appearances, surprisingly, that lack bite. Denied a point of view or much in the way of a closeup, the CG killer never feels a particularly distinctive or palpable presence, while its lunges take on a fairly predictable pattern.

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.

Kathryn Newton leads the cast in this predictable drama that is so cliched and annoying that you might just find yourself rooting for the shark.

As a horror movie, the film doesn’t have much to rely on besides the surprise of either a shark attack or loose rocks.

Of all the cheeseball shark movie that have come around as of late, The Devil’s Mouth is most assuredly one of them.

The only thing in this movie that got my attention was how can they swim with flippers, then climb rocks bare foot and not a flipper in sight. Rubbish.

This film is Quintessential Male Bovine Excrement......set on fire then stamped on with a Comically over-sized Clown Hammer.

Highly predictable. You know how it will end early on. Each next step you can see coming a mile away. Suspenseful, a little. Jumps, not really. We’ve seen this before in other movies in the past few years. I’d rather watch Jaws for the fortieth time than watch this again.

This movie is horrid💀. If u want to be angry and be able to tell the future for a couple of hours then this is the movie for you. The whole friendship is toxic the only reason most of this happened is because the Asian girl felt like she was in charge and wanted to guilt trip other people to their ever lasting death. Every hint was there on why you shouldn’t be there. 1-The cave is named devils mouth. 2-the guide on the map is red and not green. Green means go Red means STOP✋ 3-there’s no black people there. 4-the guide told yall not to go that way and said to start leaving when the shark was there. Charlie,James and the guide were the best people with some brains and IQ. Please think twice before you watch this atrocity of acting with garbage story telling and mid CGI. How is this on Amazon Prime Tubi got better than this. Thank you and GOODBYE!
