The movie closely followed the book - even including Rosalie and Jasper's stories. Bree Tanner's story added to the movie with more sympathy for her.
The acting improves with each movie, but Kristen Stewart could at least move from morose and pouty to happy - seems a bit of a stretch for her acting abilities.
Jackson Rathbone really excelled as Jasper and moved into favorite character status with us - except my daughter, who is still team Emmett.
