I sat in the theaters for 2 hours waiting until 12 so this movie would play. I wish it hadn't... This movie had many problems but the biggest problem that I had was the utter lack of a plot. The whole movie had no center it was just a bunch of random events from the book put together. The title of the movie is "Half Blood Prince", the diary that belonged to the half blood prince was only in about 4 scenes. I feel as though the movie was lacking in acting as well. This film features more tacky, lame jokes from Ron Weasley (Rupert Grint) and even more over acting from Hermoine Granger (Emma Watson). I would not reccomend this movie to anyone who wishes to go see a movie that has structure, a plot or good acting.
