I think the first two movies were great. Sure, they left some things out, but they felt pretty complete and covered the books fairly well.
Prisoner of Azkaban felt a little chopped up and incomplete.
Then 4 and 5 were really disappointing.
I really don't know what the fvck they were thinking. They made 2.5 hr movies out of the first two books, both of which were under 400 pages. What made them think they could do justice to 700 and 900 page books in the same(or less) time? Did they really think people wouldn't go see the movie if it was over 3 hours long?
So I'd be thrilled if they make the final book into 2 parts. I keep hoping they'll eventually go back and fix 3, 4, and 5 and release extended editions that are 4 hours long.
And to whoever bitched about spoilers...
1. the book has been out for quite awhile now.
2. if it's really surprising to you that there's a scene where Harry battles Voldemort or that it takes place at that particular location, then you are a moron.
