They would really need a "Dark Knight" style of Batman for it. You can't have the happy-go-lucky George Clooney type alongside Superman or they wouldn't contrast enough.I personally thought the man of steel was garbage, so yeah. But it really depends on who they get for batman because if it is the one where they fight, it would have to be someone older, not to mention the fact that christian bale's contract to be the batman is up.
I have mixed feelings about a live action movie version of a Batman/Superman fight. It works in the comics because some things are left to the imagination and you can BELIEVE that Batman has a fighting chance, and cartoons have more suspension of belief built in. Usually, Batman is portrayed a little stronger and quicker when alongside Superman or Wonder Woman, so even though Batman staggers when a thug punches him, Superman isn't able to shrug off a bat-boot to the face.
