HP and the Half-Blood Prince was very entertaining, funny even. This was surprising as the books get darker as you go from book 1,2,3 to 6. I was expecting more action centered around the fall of an institution rather than the frequent "snogging" and lighthearted ribbing that took place. Rupert Grint did display more acting talent than usual. General audiences should really enjoy this movie, serious Potter fans may come away feeling a little empty.
