Ok, we didn't have a thread for this one and I saw the film yesterday.
I liked it, it had one of the most kick-ass magic melee scenes and a great duel between Dumbledoor and Voldemort. It was certainly the darkest of all the films to date, and that's saying quite a bit after the last one. It's not so much that Potter shows his evil side, but that the situation starts to look more and more hopeless as the film progresses. It's the "Empire Strikes Back" of the Harry Potter films
