In the 2nd trailer, I'd like to see a bit more Bane and Catwomanhh!

I wouldn't say the last one was a waste of time though. It was a teaser and that's all it was meant to be. Hell, they'd barely been filming by that time so didn't even have that much footage to work with.

I don't know, I doubt Nolan would put very many spoilers in his trailers. More than anything we'll get glimpses of a story, but there'll still be plenty of questions waiting to be answered.
