I read this book a long time ago and I still have the original paperback version. The book is amazing and scares you in subtle ways, whereas the movie wastes too much time with the antagonism between characters and very little on what the story is supposed to be about. They changed the movie so much that it is unrecognizable from the book, and the casting is way off. I've waited years for a decent movie version of this book and alas, it seems I'm going to have to keep waiting. My advice? Skip the movie, read the book. You won't be sorry.
