If you've not read the books, you will likely enjoy the movie (provided you like vampire love stories), but if you are a die-hard fan and appreciate literary accuracy...you are likely to be disappointed. I enjoyed the movie, but spent entirely too much time annoyed about deviations from the book. I know it can't be perfect, but some things would have been easily fixed. Rosalie and Emmet were AWFUL. They didn't fit their descriptions at all, it was a huge disappointement. The getting ready for prom scene was cut, which was one of my favorites showing the relationship between Bella and Alice. Go, watch, enjoy, just leave your expectations at the door.
