This was a pretty good movie. I mean anything with Leonardo DiCaprio in it is going to be amazing to me. The film is based on a book that is exactly the same according to Sunshine. We watch Teddy, a US Marshall on an island for the criminally insane looking for a missing patient. In the end we find out that he is actually the patient. He was brought there because he killed his wife. What! He killed his wife. Yes, because she drowned their three children. This adventure is a wild ride and by the end of the film things start making sense when you think about what you saw earlier in the film. I give Shutter Island 4/5 stars for having Leo but if I am rating just the film I give it 3/5 stars.
