Overall Rating: 10 Harry Potter and the Half-Blood Prince is a very well crafted movie and the best one of the series to date. The task of transforming a book into a movie is a difficult task even more so with the depth, length and multitude of fascinating subplots that the potter series contains, my hats off to Steve Kloves and David Yates for an outstanding job. In the Half-Blood Prince they fully used the movie medium to make this movie stand on it's own, it's the first of the movies that does not require the audience to have read the books to get the full story.
