Well i have oficcially finished all the books and have just finished watching the movie... and ... well... I have to admit the books are way better - but I did enjoy the movie!
I think what bothered me the most about the movie is it doesn't portray Edwards confidence very well. To me in the book he seems very sure of himself, and he seems the complete oposite in the movie!
Otherwise, the characters have been picked out quite well! Can't wait to see the sequels!
