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.

1.5/4

It’s been hyped as the first fresh-water shark movie. Sad to say, that’s the only thing fresh about it.

It’s just aggressively forgettable instead of memorably awful, which is almost worse.

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.

I'm not sure how you make a 'The Descent'-but-with-a-shark movie boring, but 'The Devil's Mouth' proves that anything is possible.

Newton and Condor deserve better than what the script provides and one wishes the different caves were more distinct, but as a pale imitation of The Descent (with a shark), this is dumb fun.

So no, the shark isn't the scariest part of this thriller. Nevertheless, The Devil's Mouth was entertaining to watch, if you have nothing else to do on a Friday night.

The devils mouth is very intense and not much of a true story but it was very good

I’m fairly certain this is one of the worst "horror" movies I’ve ever watched; however, the entire movie was so dark – due to lazy filmmaking, low budget, or both – that I couldn’t make out enough to be sure. Super ridiculous waste of time all around. Not even mildly good in a gore/campy way.

This movie seems to have been lit with an itty bitty book light. A bold choice and a terrible choice. Maybe it would have been good if I could have seen what was happening.

Such a dumb AI shark. Bunch of idiots screaming. We rooted for the AI shark to kill those kids. The way it hunts the characters inside those narrow tunnels is completely rubbish!!!! sharks cannot swim backwards yet it shows the shark backing out of tight spaces hundred times so it can keep attacking.. nonsense. RUBBISH movie.
