I also think that the movie is a bit choppy. It's like they are trying to make the movie to fit the 2 hr time frame.
The huge disappointment came in the form of the wolves. They are made to look like a very likable furry dog which is slightly bigger than the normal sized dogs. If you read the book, you would be picturing the wolves to be really huge and very strong looking and have a nasty look on their faces once they are fully morphed. The one in the movie ... they look very close to over sized furry dogs. Quite cuddly. Nothing werewolves about it. :(
