I absolutely loved this movie! This is no logical or scientific masterpiece, but you shouldn't expect that either. The action is over the top and crazy, but the movie is an edge-of-the-seat entertainer to the end. Not a single boring moment, and some thrills will probably even make you gasp (as it was for me). Highly recommend on the big screen, especially if you love shark movies. Go, even if you don't, you'll still like it.
