Re: "...a man who is older and wiser than Clark Kent": Does this not worry anyone els
I think this will go the route of the Stark/Cap relationship in The Avengers, which is fine by me. It will start out with Batman being the cocky, arrogant, seasoned badass that we all know he is, and he'll have the attitude of, "Oh, so you've been blessed with superhuman abilities? Big deal. I'm trained in every martial art known to man, I'm the world's greatest detective, and I'm a billionaire industrialist. And I've been doing this sh** for a while." But the more they work together (after duking it out) he'll come to see Superman for the hero and true leader that he is (and essentially, the out-in-front figurehead that Batman can never really be), and he'll earn his respect.
