I saw this on imax, but we were in the third row, and off to the left - I couldn't really tell the difference in experience - maybe I have to see it in a regular theater now to compare. But some parts, especially the sonar bits, made me dizzy - there was so much going on my eyes couldn't focus on anything. So if you go see it in imax, get good seats!
I loved Heath Ledger's Joker - definitely lived up to all the kudos people have been heaping on it - and such a pity he's gone

I can't think who could take his place - maybe Johnny Depp?
I thought that Two-Face's make up effects distracted me too much from Aaron Eckhart's acting - though I know that's how he looked in the comics.
I was annoyed (again) by that horrible voice Christian Bale had to use whenever he was Batman - I think the worst lines in the movie fell in his lap, sadly. It felt like everybody else had more character development than he did.
And... when was Batgirl on the phone??
I have a feeling everybody in Chicago's gonna be owning this dvd

It was pretty awesome to see all the familiar landmarks everywhere. I also noticed that this movie was brighter than the others - a lot more daytime scenes.
Favorite scene is probably the nurse outfit and hospital scene
