I loved the movie. Now I'm one of those weird people that actually like the last three books, more so even than the first four. Yes, I know that a lot of people disagree on that, and I don't care.
(I also like the epilogue of book seven and I can't wait to see the kids they pick to play Albus and Scorpius for the last movie, nah)
But I have to say, even with all that, I loved the sixth movie even more than I already liked the book. I think the one thing I liked most, is how real the visualization, made the threat of the Deatheaters. The attack on the bridge, the attack on the Weasley homestead, ...
You could really see the threat building.
I loved the actor they had playing Slughorn, Snape and Draco were good as ever.
But as ever, my fave character is Harry Potter himself. From the start of the movie to the end he captured my heart and held my full emotional attention up to the last moment of the movie. I loved Ron and Hermione, and even Dumbledore was aweome.
I can barely wait to see the last two movies, though I do wonder how they'd manage to get two movies out of the last book. Just hoping they won't drag out the camping too much. (you know, so people don't start complaining about it too much)
