I have read all the Twilight books and absolutely am a fanatic. No movie will ever capture all the magic of a book and sometimes they try too hard. In this case, they did about the right amount. They stayed pretty true to the book except in a few cases which really were necessary for non-twilighters to get into the plot. The action was pretty good and the actors all did a great job at their characters. Kristen Stewart was perfect as Bella. In fact, before I heard of the movie I thought of Kristen Stewart as Bella based off her performance in The Messengers. If you liked the books and understood the teen angst and also the angst of a loner such as Bella, then you will absolutely enjoy this movie!
