As always the books are way better than the movies, but as a prior reviewer said Stephanie has so much detail in the books you cant cram it all into the movie, its impossible. I have read all 4 books 5 times (ya, I have no life I guess) I get 'Edward withdrawals' and just have to read them again, loved what she put up of Midnight Sun and cant wait for the book to be completed next year!
That said, The movie rocked! I cant wait to see it again! Its really great and less cheesy than Twilight, which I thought could have been better (but again, look at the book in comparisson, had I not read it would I think that???)
