Favorite and Least Favorite Harry Potter Book and Movie?

I don't really have a favorite book. I loved all of them. But the movies. Prisoner Of Azcaban was my least favorite, but only because they left a lot of stuff out that could have been in the movie if they hadn't put in so many shots of the stupid womping willow. There were like four scenes just of the tree. No characters or anything useful. Just the tree. Sorry. That just annoyed me.
