I've never been much of a fan, but I'm willing to give him a chance.
Bruce Wayne dressing up like a bat to help Superman save the world bothers me. Batman works all dressed up in Gotham, striking terror in the heart of his enemies and such. Bruce Wayne and Clark Kent work. Superman and Batman is strange.
I can hear General Zod say : "Why is that human dressed like a bat?"
Seems like they're going for a more experienced/established Batman, so he's been dressing like that for a long time...why change his clothes to team up with Superman when there's finally somebody else to play dress-up with?
And General Zod won't have much to say about it, considering he done got his neck good and broke.
