Excellect cinematography, great transitions. Tom Riddle & Horace Slughorn are perfectly cast-- and Michael Gambon gets Dumbledore just right (finally!) Most of the comic relief was well placed-- however I could have done without most of the awkward teenage moments. Some dialogue could have been added about the purpose of Dumbledore and Harry's meetings, as well as ideas about who the Half-Blood Prince might be, and what kind of person he is (brilliant? or just evil?) Unlike some of the other movies, this one hints at important things to come, and seems to attempt to connect to things that happened in previous movies. Overall, incredibly well done-- I can't wait to see it again!
