All the Potter films I've seen - the first 3 - were disappointing and since avoided like the plague. Just one of those films where the books were more interesting.
Harry Potter and the Half Blood Prince
I went to the midnight showing, I was stoked because I thought the last two movies were amazing but this one . . . this one just failed miserably. I felt like I was watching an episode of the Gilmore Girls wrapped in a thin layer of Harry Potter.
