One thing I was wondering, however... and this isn't really a spoiler I don't think cause it's in the book, but it's a little different in the movie so I'll cut it anyway...
During the scene where Harry is seeing Snape's worst memory, and James is dangling him upside down, the rest of the kids are chanting something. What is it?
On a related note, I was just talking to my brother about how awesome Alan Rickman is. Anything he's in, doesn't matter if he's a bad guy or a good guy, you either love him or you love to hate him.
ETA: I was looking at my mood icon and I just had to add...
THANK YOU DIRECTOR MAN FOR MAKING THEM GET HAIRCUTS.
