I do not remember the book, sad to say, it's been a while since i've read it. watching the movie reminded me what was going to happen. the only negative thing i can say is that there was no history with some of the characters, Bill and Mandungus... also, i thought the very beginning was a bit confusing. i had to think really hard about what happened at the end of the last movie to remember what was going on, i almost think they should have reminded us that the 3 were not going to hogwarts instead of just umping into the story line.
