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.
