Well, I went to see the movie twice. This was not intentional. Overall, I think the movie does a pretty good job of representing the book. However, there are things I didn't like.
Bella arrived in Forks in January not March. They didn't make it look cold enough. No big parka on Bella. No snow. Bummer.
I really got tired of looking at Kristen Stewart's mouth. How many close-ups of her mouth does 1 movie need? If her mouth wasn't hanging open, she was biting her bottom lip.
They left out a few of my favorite parts. The scene where Edward kisses Bella on the stairs and she faints. The blood typing and subsequent fainting in Biology. I'm hoping these scenes will show up in the deleted scenes when the movie's released on DVD.
I can't say I was too happy about the actors who portrayed Bella & Edward. I'm not sure who I would cast if I could, but there have to be actors that better fit the characters. Edward didn't dress as well in the movie as I thought he should.
I loved the music in the movie. After I saw it the first time I rushed out to get the soundtrack. I think I'll eventually come to the conclusion that while I'm not entirely happy with the movie, they did a pretty good job condensing a 500 page book into a 2 hour movie. I definitely like the book better.
