My girl has been obsessed with the books for months and I never understood it. (I'm not a reader) I was really afraid this movie was going to be a chic flick, but I have to say it's the best movie I've seen since "I am Legend". I dreaded even the thought of going to see this movie, but I was by far wrong. YOU DONT HAVE TO READ THE BOOKS TO UNDERSTAND as the previous poster suggested. They done a great job at implying what was going on and I'm looking forward to the next.
