We liked it! We're going to visit the Simpsons tomorrow!
Definitely could have been a bit longer, good as it was. I'd have enjoyed a little more Lupin and Tonks and if it was revealed that Umbridge sent the Dementors after Harry, I missed it.
And there should have been the payoff to the scene of Harry's father tormenting young Snape. Maybe they'll put out an expanded edition on DVD.
Lance, I thought that scene was way too short, particularly in light of how important it was in explaining Snape's future behavior toward Harry.
I was just thinking that each director must have been begging Rowling for hints as to what was going to happen so he'd know what to foreshadow.
