A somewhat mis-matched crew are working on a base deep underwater when things start to go wrong. An earthquake right at the bottom of the Marianas Trench - or was it? Kristen Stewart ("Price") and Vincent Cassel ("Lucien") lead a team who have to escape their collapsed facility and make it to a nearby abandoned mine where there might be a route topside. The film features the usual lines of jeopardy - will they drown, is there enough oxygen, etc - but somehow, even when we discover there is much more to the disaster, the menace just floats away. Stewart is really underwhelming, as are the rest of the cast and is the writing. The visual effects are adequate, but that is standard nowadays, it's the story and characterisations that are just flat. It is only 90 minutes long, but it seems longer and somehow the ending was just a bit, well, damp! Can't think this ever got a cinema release - that might have helped, big screen and all that - but otherwise, this is entirely forgettable fishy fayre.

**Overall : An exhilarating and tense high-stakes survival movie where the creatures are only one of the many horrors to be survived.** I can't lie - I LOVED THIS MOVIE! Underwater is the spiritual follow-up to the Alien franchise. The intensity of every claustrophobic second grips the audience as the characters fight to survive overwhelming obstacles to emerge from the ocean's depths alive. The dive suits, narrow corridors, limited visuals, and terrifying creatures add to the suspense throughout the film. The director displays his incredible skill at building tension and anxiety every moment. I don't know why this movie has such low reviews because I was captivated from start to finish.

Great watch, will watch again, and do recommend. To be fair, I was sick when I saw this was available and couldn't resist watching it. I'm a fan of Kristen Stewart (most of the time), and sure, she runs around in her underwear for a lot of the movie, but that's not a reason to watch the movie, it's a horrible reason for a web search. A great reason to watch this is that it is a underwater survival story. The isolation and technical strategy involved in dealing with this situation makes it gravely atmospheric, without the threat of "monsters". Honestly, that version would have also made a great movie. The movie clearly takes queues from several other great movies, and while it does it very well, the problem there is "several". Had the movie mirrored only "Alien", it probably would had been a stronger story. Clearly the writers wanted the threat to build, similar to video games, or possibly more similar to an alien invasion movie. The cross between a survival / slasher movie and an invasion movie muddles the feel of the movie somewhat. It downgrades the movie from truly excellent to great, and I don't feel that everyone is going to get the proper experience to recognize all of the great individual parts because the overall pie tastes a little funny.
