I'm not going to say it was great, because as other people have stated, they left things out. A lot of backstory was dumped for the sake of progression, so you missed the Lupin/Tonks storyline, Harry's dad wasn't brought up at all, and Ginny's romances with other people were kinda glossed over, etc, and they changed some parts in comparison to the books, ie the end. There were a few slow parts in the movie, but they were necessary for the story sake of it, and if those parts were rushed it would have made the movie overall seemed rushed. Overall, I enjoyed it, I'm just glad the last movie is split in two even though the book was predominately very slow in action.
