i am an avid fan of the harry potter series; i read the books as soon as they come out. watching the movie is invariably in comparison to this experience. I think that in the instance of Harry Potter, Half-Blood Prince, the movie plot left many holes that only those who had read the book could fill in the gaps, and those who didn't, like my companion last night to the premiere, were left bewildered and apathetic. The other movies were more works of cinematic beauty. I feel this one stunk of twilight-esque teen drama.
