Considering the amount of events in the book the movie was based off of, Harry Potter and the Half Blood Prince was excellent! The musical score was very well put together. The special effects were great as well. Even if things didn't look EXACTLY as they were described by J.K. Rowling, I think readers and non-readers alike can enjoy this movie. Yes, certain events that were present in the book were not present in this movie, but it is only a 2 1/2 hour movie; they can't put everything in exactly the same. Overall, it was "pottertastic"
