I would have went with four stars, but any Sparticus Blood and Sand alumni gets an extra star. So, it's basically a slasher film with sharks. Very bottled with the majority of the movie taking place inside of a boat. However, it manages to be super cool and stylish. I normally dislike slasher types, but I was glued to the screen the whole way through, and there is a couple scenes that really hurt to watch, in an awesome way. Definitely a movie to see.
