If I'm going to be completely honest I fell in love with the books.
They were brilliantly written. Packed with detail. They are a brilliant way of escaping the real world and being engulfed by the fantasies of Vampires, werewolves and gorgeous, strong men. Perfect for a girl of sixteen with a wild imagination!
edit: unfortunately I watched the film before reading the books, which very nearly put me off the film. I wasn't happy to find that had skipped out some, unimportant yet, interesting details that were in the book (i wont give them away in case someone is waiting to read them). The only thing that kept me hooked to the film is the wonder that is Robert Pattinson.
