As a devoted fan to the Twilight series, I was very nervous about seeing the premier. I was afraid they were going to kill the book very much to how they killed Eragon. But I absolutely LOVED the movie. It followed the book very, very well. There were some cheesy points that the director added in to add drama and the "essence of love", but it just made me laugh. I loved, loved, loved this movie! However, I do recommend reading the book first. You don't have to, you'll still love the movie I believe, but it helps. :]
