Twilight was full of action and awkward moments, like those between Edward and Charlie, but important bits were left out from the book that made Bella seem much less close to the Cullen family than she does in the books. There were also differences between the book and the movie that affect the dynamic of Bella and Edward's relationship in a very big way during an important decision for Edward. While so much was left out, the relationship between Bella and her mom was shown a lot better than it is in the books. Stephenie Meyer's cameo appearance is blatantly obvious, so don't worry about missing it. The movie was overall very good, but in comparison to the books it left a lot to be desired.
