Average movie with average actors. Wouldn't expect to see Jude Law in this role and hardly understand why he accepted being part of this. The tension in the movie is very low. I've seen submarine movies that kept me in suspense till the end; this one wasn't capable of that. A very straight story with no good twists and way too predictable. The cast was alright and Jude Law is a fine actor. The atmosphere was alright. It really seemed that they were on an claustrophobical piece of machinery. Yet, the claustrophobical guy acted as normal as the next guy. Didn't like that. It's not a bad movie, but it's not a good movie either.
