I think the movie was really good, considering a lot of stuff had to be cut out for time reasons. I am a bit disappointed that Jasper, Alice, and Jacob were cut out quite a bit...
Also, there are quite a few scenes that were kinda cheesy and the special effects could have been done a bit better (Edward's sunlight reveal, for example), but I liked that Bella was more confident of herself in the movie than the book. And the location scenes were visually beautiful. Overall, I enjoyed the adaptation.
