I'm with you there. His suit material looked awesome in MOS but it was at times just flat out goofy looking in BvS. Particularly when he walks up to the podium at the Senate hearing. I can totally see someone adding those "eee, eee, eee" squeaky noises like they did for the "Oops I did it again" Britney Spears video.
You really are confused about the Batman/Superman brawl aren't you?
Let me break it down for you:
1. Batman hates Superman, wants him dead.
2. Superman doesn't like Batman's methods so he tells him to stop and to ignore the batsignal.
3. Bruce says, "aha, batsignal, that's our battleground, I'll go set a bunch of traps around it and turn it on so he comes to scold me again. When he does I'll kill him."
4. Lex tells Clark his mom will die if he doesn't fight and kill Batman.
5. Clark says that sucks, what a dilemma, let me go tell Bruce about it and see if he'll join me. It's not like he can hurt me or anything.
6. Supes sees the batsignal and goes to talk to Bruce.
7. Batman says, "ha ha, sucker, you fell for my trap, try and arrest me *****."
8. Superman isn't there to arrest him at all, wants to talk, but doesn't really have a lot of time to **** around. "Look if I was here for a fight, you'd be dead, can we talk?"
9. Boom, Bruce hits him with kryptonite, Supes says "WTF???" and literally is forced to fight for his life.
Did you really, REALLY not understand how that all evolved? Because it was definitely one of the aspects of the film that was *not* vague.
