Well, I saw it and I think we were really spoiled just because we are BAT-FANs that we knew more about general facts about characters that the normal audience didn't know.
I can't choose a definitive surprise moment but is was done and directed in a matter that I was impressed. and even though there really wasn't a definitive surprise moment for me, there are a ton of WOW moments and I did feel real emotion, including a tear or two because so much is going on...and then (just like with the boards) you sense an inevitable feeling of the end (by that I mean of course...no more Nolan Batman Films) but he didn't let me down. I did have a good time, too.
I can't wait to watch the Dark Knight Trilogy with my child...when I have one. That's how good it was.
