I am a HUGE Twihard & LOVED this movie! I don't think you can ever fit all the details of a book into a movie script. However, I feel that Chris Weitz did an excellent job directing all the action / emotional depth that appeared in the book. I also think he included all the major events that happened in the book. I HIGHLY recommend seeing this film if you are a Twilight lover. I can't wait for ECLIPSE and will be in-line at the midnight showing.
I LOVE this movie! It was the perfect thing to watch before seeing the midnight premiere of NEW MOON. Twilight is a romantic movie with sweeping visuals. I also think that the chemistry between Rob + Kristen is palpable. Go rent it & if you've already seen it, rent it again!
