Holy Crap, I loved this movie SO MUCH. I completely agree with you though about the Snape/Harry showdown at the end. I NEEDED those lines from Snape. The 'Don't you dare call me a coward' and 'You're going to have to to better than that!' I also needed Snape teaching them the important stuff in DADA because that's also a clue about where he's really loyal.

However, the conversation between Dumbledore and Snape made it all seem pretty obvious to me.

anyway, loved it loved it!!
