As a sucker for sharks, I could not help wanting to see this despite the trailer. However, the trailer perfectly sets up expectation for this movie. This movie will be dumb, but there will be sharks. And surprisingly, the movie wasn't quite as dumb as the trailers might indicate. It a pretty straight-forward worst case survival scenario with sharks that actually ends up having some very fun moments. Until the ending, the ending attempts a twist ending that doesn't really need to be there. In fact, the whole disjointedness of that tacked-on twist diminishes what is otherwise a decently fun, dumb movie with sharks. However, the sharks are great. If you like sharks, you'll probably be looking for reasons to like this movie despite yourself, because... Sharks!
