1)Eisenburg is a shit Luther. He comes across as an Emo Nerd who needs to get laid.
2)Some of the dialogue is face-palm worthy, especially the, "you do not want to pick a fight with this guy!" and "you know the oldest lie in America..."
3)Doomsday, one of the most iconic villains in comic book history, looks like the product of an violent, drunken hate-fuck between Tim Roth's Abomination and a Ninja Turtle.
4)Even if they'd made a great Doomsday, which they sure as Hell haven't, they shouldn't have shown him during the trailer. Keep your powder dry for the movie itself.
5)WTF is Batman and Superman's problem with each other anyway? Superman doesn't like it because Batman tortures criminal scum? Really? The same Boy Scout who snapped Zod's neck? Add in the collateral damage of his fights and Superman has a way higher body count than Bats.
Batman's hate-boner for Superman doesn't make much sense either. Batman is supposed to be a cold-blooded, pragmatic, strategic genius. So why can't he figure out that Supes wasn't to blame for the carnage? Indeed, he saved the whole world, even if it did come at a price.
