Superman moves to Gotham

What happens? And it's not a part time thing but rather permanent. Does the town change? Do the villains change?

Superman is great at stopping big crushing enemies.  If Bane or Croc were to show up doing something, superman could stop him pretty easily.

Unfortunately, many of Batman's enemies are more subtle.  They enjoy conspiracies, and they're unafraid to plan things out quite a bit.  They'd find ways to frame superman for evil deeds that would make Luthor jealous.

Sure, nobody would believe that Superman burned down the *first* orphanage, but after every orphanage in Gotham burns down in quick succession as soon as Superman gets near it?

Superman is strong, and he's not stupid, but he's far from truly cunning.  He'd bust a lot of small time crooks, possibly some of the bigger problems, but in the long run he'd be eaten alive.
