Yeah, they had the Halfblood prince but dude... They completely skipped over Dumbledore's funeral. I was so very very disappointed about that. The funeral was one of the most powerful parts of the book, in my opinion.
Not to mention that at the end, when Dumbledore took Harry to the cave, it was -not- their first meeting. Dumbledore had been taking Harry into secret meetings for months before that meeting, but in the movie, they made it all "Oh, this is so sudden, we don't meet like this" yadda yadda. I was incredibly annoyed with that movie.
Don't get me wrong, Daniel Radcliff is a fantastic actor, and they have a great acting team. But there was too much from the books missing in order to fully enjoy the movie.
