As with all the others, the cinematography was beautiful and the acting was spot-on. I really enjoyed the addition of Jim Broadbent as Slughorn; he really nailed the part. However, I do have a couple issues with the movie. Firstly, to be called "Harry Potter and the Half-Blood Prince," they didn't focus much on the Half-Blood Prince or the potions book. Second, two of the book's most pivotal scenes fell sort of flat on the big screen, losing a lot of the drama and emotion that made the book so incredible. Aside from these gripes, the overall movie was well done considering the amount of material that had to be covered. Good job, guys.
