Superman has killed aliens before. I recall reading this in a comic when he was talking to batman about killing aliens. He has just never killed a human being before though. So him killing Zod wasn't uncharacteristic of him. And the fact is if you want a movie where superman goes all out, then civilians will die and collateral damage will be taken. that's a simple fact of life that when two god like beings fight, s@%t hits the fan big time. And in those fights, you don't want the good guy taking his eye off the other guy to look out for innocents cause then he'll get killed by the bad guy. Its like in war when soldiers have to keep fighting on even though they see their fellow soldiers die in the crossfire. it's sucks and is horrible but it happens and is realistic even for superman because he is facing soldiers with the same powers and abilities as him. Criticism based on that is only warranted if supes was facing an easier enemy like lex luthor or cyborg superman.
@blackarmor: Well I agree with your other points but Wildcat isn't coming to Batman/Earth 1 anytime soon unless its some cross dimensional thing. Even though he hasn't been in costume or anything, he's been mentioned/shown in the Earth 2 comics. Personally I wish DC expand the whole Earth 2 universe already, there are so many spinoffs based on that comic just waiting to happen.
@.Ajax.: They chose hawkwoman over hawkman to add more females to the game. And Hawkwoman is an obvious after WW because she was in cartoon JL. I mean out of those WW, what other women can the DC put in the game that is instantly recognizable to the general public?
