it is early footage, you're right. that didn't stop them to show it attached to a finished movie (cap) so everyone can see it. which means those producing the movie are pretty confident that this footage is good. It is not. It's the opposite. It looks cheap, terribly cheap.
and the reason for that are those godawful costumes. It's like the first green lantern trailer, you could see how they went into the completly wrong direction right into a disaster.
Don't get me wrong, maybe they are able to fix the problems, maybee they reshoot this part, maybe this movie is not the cheesfest it looks like right now. But there is no indication for that.
Almost a year ago I had a hunch TDKR would be a terrible, terrible movie. And look where we are now: We have a movie about BANE. B A N E !!!! And the Lazaraus Pit probably too. So it turned out that I was right.
