After having read all of the Harry Potter books and seeing all of the movies out, Harry Potter and the Half-Blood Prince was definately my least favorite movie so far. Many details were left out, a fight scene was added, a fight scene at the end was non-existent, and key parts of the book were either left out or changed. There are also many quotations of characters speaking directly out of the book, but it got annoying because they were out of place, and some weren't even said by the character who made the statement in the book. Overall, I was highly disappointed and the movie was not worth all of the hype that it received.
