If I could make a suggestion, before you see the movie to read the novel. It is some of the fastest 600 pages you will ever read. While I found the movie good, and somewhat faithful to the book, you'll be left feeling like the movie went too quickly. The movie literally goes off like a machine gun. The book takes care to describe everything that's happening to you, and really keeps you going from beginning to end, describing everything that goes on in their heads as well as on the island. I've read the novel, watched the movie and I'm reading the manga as it gets translated to English. They all tell the story in very different ways, the manga having the most shocking levels of sex and violence. They change a few things around between each translation, and each form is enjoyable, but I personally like the novel best.
