A lame attempt at a suspenseful movie I could go on a five-page rant about the many, many failings of Deep Blue Sea, but I'll restrain myself to a brief rundown. The premise is decent - Not unlike Jurassic Park with sharks. The rest of the movie is a greater letdown - the dialog ranges from half decent to god-awful, the plot devices are not only unlikely, but downright impossible, the acting is lousy, and the writing is atrocious. Not only does this film suffer from an extremely poor script, but also a simple lack of care on the part of it's makers. Some examples range from having a huge, fragile plate glass window 50 feet underwater, to a character running DOWN STAIRS to get away from flooding waters. If someone with a little knowledge and experience had written this, it might have been much better. Unfortunately, the acting isn't much better. Saffron Burrows, while being quite pleasing to the eyes and ears, seems to lack any acting talent whatsoever. Thomas Jane isn't much better. Samuel L. Jackson is good, but he gets about 10 lines. I can only assume he did it for the money. There is one really genuinely startling and scary moment in this movie - if you've seen it, you know what I mean. But unfortunately, it isn't worth it. If you want killer critters, watch Lake Placid or a Jurassic Park movie.
