I considered this movie to follow the books the best. I think it might be because they've opted to split it into two movies so they can fit in more of the details. I was not disappointed at all! I love how they can get the seriousness into the movie as well as a laugh here and there. Of course there are some of the details missing, but overall I think they hit the main points. The cast did another amazing job, and I love how they kept Dobby the house elf in this movie, especially since he's been cut out of some of the the other movies. So, go see the movie...it really is incredible!
