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 Travers Take

2d

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.

The Devil's Mouth is one of those "I hate all these characters and can't wait to see them die" movies, but not in a fun way.

At some point you just want all of them dead. That point came 5 minutes into the movie.

Unless you like looking at pretty people in gorgeous locations, you will die of boredom for a survival thriller movie without thrills.

Absolutely terrible. I would give it zero stars if I could. Every aspect of the movie was completely predictable, yet somehow still wildly implausible and unrealistic. I genuinely don’t understand the point of this film. On top of that, it was disgusting. Do yourself a favour and don’t waste your time—DO NOT WATCH THIS MOVIE.

If it wasn’t for Katherine Newton, I wouldn’t have watched this. I’ve liked her in past films, this time was by far the worse. And I don’t think it was her fault. This is a monster horror survival film, that has been done many many times. Nothing unique or exciting about this film. It was quite boring. It kind of gave the descent vibes like they were copying them because of the caves and the main characters having tension and possibly betraying one another, but difference is, descent had unique monsters , this movie was just a shark. Just one! And acting and story behind it was much stronger and original. This film just felt very cookie cutter and rushed. Even the ending was boring. Didn’t feel like a real ending just very bland and forced. No emotions. Wouldn’t want to see this again and not worth seeing the first time. The only reason why I gave it a 2 star is because of the lead actress. The CGI was sharknado quality also!

A very good movie about how to be a terrible person and so called friend. From the get go, max shows that she is an awful person who deserves to get eaten by a shark.

This movie continues the tradition of so many movies based in Thailand being rather weak. In this case, a group of youngsters embark on a risky jaunt into a cave. There are unmistakable echoes of Neil Marshall's excellent "Descent" here both in the cave location and character development, which may have been a heavy inspiration here. Sadly, this one falls a bit short.
