I'm disappointed in the "Half-Blood Prince". Always in the past the movies have stayed with the books and it has been my understanding that this was as per JK Rowling's wishes. I'm wondering if she got to see this movie before it was released! There were ommissions that I felt were a major part of the book. There were changes that just left me asking "Why?" and scratching my head. I don't want to spoil it for the HP fans that have not seen the movie yet, but for us die hard fans, it was disappointing.
