Re: "...a man who is older and wiser than Clark Kent": Does this not worry anyone els
Superman coming across as Robin might be the most ridiculous concern people have had yet.
He's Superman, who has been saving lives for much of his life. Not a teenage kid with no experience.
I think the "older, wiser Batman" thing is an interesting and appropriate dynamic, as that's kind of always been the tone struck between Batman and Superman in modern comics anyway, even despite their closer ages. They've got something to teach each other, and more in common than they think. Batman has a more methodical, strategic way of doing things, and Superman isn't the cynical fellow Batman is, he operates with more hope for humanity.
