I did not enjoy Harry Potter and the Half-Blood Prince. While I understand that movies sometimes have to stray from the story in the book for filming purposes, I feel like this movie was nothing like the book. Yes, some of the parts were out of the book, but as a whole, the movie did not follow the book. The first 5 movies were much better at following the story line from the books, so I was very disappointed when I watched this one to see that it was nothing like the others. It was a good movie, if you haven't read the book. If you have read the book, be prepared to constantly tell yourself "That's not how it happened in the book" or "I don't remember that happening in the book."
