left out lots of details from the book. Not a lot of action sequences here. By the time the movie ended I was still waiting for things to pick up. And, to boot, the title of the movie "Half-Blood Prince" would seem to indicate a major theme. Well, this whole storyline seemed secondary or even tertiary throughout the movie. Close to the end, Snape simply admits being the Half-Blood Prince, but big whoop---that's it? Exactly what did that whole storyline contribute to the movie overall? As with all Potter movies, the CGI is spectacular and the cast has matured very well, becoming solid actors. But, this particular movie just left me feeling unsatisfied.
