Director David Yates, while not able to include all of the book's details, stayed true to Rowling's intent in the Half Blood Prince. Snape's vow was given its needed emphasis, the horcrux meaning was explained, and the discovery of each of them was exciting. The memory sequences of young Tom Riddle captured his calculatingly evil childhood. It was also nice to see a bit more from Alan Rickman. And Draco's character became less the cardboard bad kid and more three-demensional -- better than J.K. did herself, I thought. I would recommend this movie to all fans of the book series. Now, let's hope Yates can beef up the last rather boring part of othe sequel.
