I'm awed that New Moon could be anyone's favorite. I read about a novel a week, and in my lifetime I have read over 300 books. New Moon was the worst book I've ever read in my life. Having read a LOT of books, I can say that's pretty bad.
I liked Eclipse best, although the entire series was mediocre at best. It is tragically overhyped. The characters are static and the story is melodramatic. Not to mention I think it is a terrible romantic model for young, impressionable young girls. Edward is a controlling creep. I would not want any daughter of mine worshiping this 'Saga.'
I am twenty, by the way, if it makes a difference.
