While I don't think that a movie can ever truly capture the depth and detail of a book, I think that Twilight did a great job in bringing the story of Edward and Bella to the big screen. Many scenes and dialogue were shortened, combined or changed, but the alterations didn't really change the plotline too much from that of the book. I think that the changes made were for the sake of time to ensure that the story was represented in the 2 hours of the film. I thought casting of the main characters was excellent. Edward and Bella were just as I pictured them. I really hope they go on the adapt the remaining three books.
