It's not quite as bad as I remember it being, but there is a lot that should have been, could have been cut, to streamline things a bit.

Batman feels like a bit is an obsessive psycho. Plus he spends the entire movie hating Superman for all the collateral damage from Man of Steel, then leads the big bad, right to Gotham. I guess Gotham is full of criminal scum and doesn't matter? Where did Gotham come from anyway, suddenly it's right across the river from Metropolis?
