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.

1.5/4

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.

It's moody, deeply atmospheric and packed with enough claustrophobic tension to keep you on the edge of your seat or, if you're anything like me, completely cowering behind your hands in the dark.

Stupid, annoying and hard to see might be the holy trinity of crap.

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.

Utterly and abysmally stupid from start to finish. The damned cgi shark changes sizes throughout, apparently has Moby Dick ramming powers that rival Juggernaut and can eat 7 people in less than an hour. Let alone that Bull sharks are rare in Thailand, stay in deep currents, and would never be washed into a shallow riverine cave without a sea outlet regardless of any stupid storm surge. Somehow a seabird just dies from swimming in fresh water? Red tides affect an inland river cave and saltwater bioluminescent plankton just casually thrive in the same freshwater cave? How does anyone write such a stupid story and actually get it funded? This is why we can't have nice things!

What an insufferable set of characters in such a boring film.

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.
