Shutter Island was one of the most well crafted psychological thrillers to by since Silence Of The Lambs.And it is not coincidence both were brilliantly written novels.The story follows Teddy, a federal Marshall and his partner Chuck(Played by Leonardo DiCaprio and Mark Ruffalo).They go the mysterious island enveloped in fog to investigate an escape.From these opening scenes, Marty has set up dark and creepy premise.Almost the whole movie incorporates this story as Teddy desperately tries to find the truth he seeks.But the end was shocking and most interesting part of the movie.Cast performance was so good specially Leonardo DiCaprio, Mark Ruffalo and Ben Kingsley.
