I read the book first, perhaps that spoiled the movie for me. While the film follows the book fairly well, it misses out things, such as the depth of Bella's emotions, especially during the Jacob kiss scene, and afterward, and during the fight with Victoria, who is played by a much less threatening woman. She didn't give me the creeps at all, she rather looked kinda cuddley.
I hated the line, "Well, I am hotter than you" by Jake in the tent. That is not said in the book and it was lame. I was dissapointed by Taylor Lautner's acting in this, I just did not believe him. He was just some kid. Nor did I believe Bella's "love" for him.
The violence is pumped up in the film from the book, more senes of it, though it is not gorey. Vampires are killed without blood, as they shatter like in the book. Everything runs along rather quickly, scenes mushed together. The Volturi were not threatening, and seemed to me like kids dressing up and playing in the yard with a video camera.
Charlie on the other hand is thoroughly believeable and one of the best acting jobs in the film. I really liked the "little talk" scene. I was also satisfied with Robert Pattinson's acting. Shame they couldn't find a pretty ring, that one they used looks like something from a garage sale.
I liked the flashback sequences, Peter Murphy was frightful as the original cold one in the area. Costume of the Quillettes was also good. And it tells the sad story of Jasper's past as well as could be expected.
Overall I thought the story was dumbed down for a younger audience. I am 36, same age as Stephanie Meyer, and I enjoyed the book, and don't see why the target audience for the movies seems to be 13/14. It deserves better.
