I'd love it if Luthor says something to the effect "You cannot stop me. You have no evidence, no frame of reference. The only way you can stop my war against you.. is to kill me. You've done it before. What's stopping you now? You can break my neck, and slip out of here quietly. With your speed, no one will see you leave."
And then Lex saying something like "I knew you wouldn't. You act tough, but inside you're just another boyscout." And then Superman threatens him vaguely, but awesomely.
Lex responds, "I don't have to intimidate people to get what I want. Give them what they desire, and they'll do anything to protect me."
"What have you given them? False hope? A city in ruins?"
Etc
Meh. I realize this is maybe what some of you want, but that just is clunky and awkward, and would look awful on screen. I want Superman to be cool, not to be cheesy and campy.
I don't need a huge exposition on this whole idea of Clark not wanting to kill again. It's clear in MOS how horrified Clark was by what had happened. Why do we need to devote a film to that particular idea? To assuage the ******** fanboys about Superman having to kill?
No thank you.
If this were a television series, I might be all for Clark having some PTSD, and I'd want to wring every drop of hurt/comfort nonsense I could out of killing Zod. But this isn't a series, it's a movie. I don't want an entire film devoted to Clark having issues, nor do I want to see bad guys prancing around on screen, and trying to use Clark's desire not to kill against him.
It would be better if maybe Superman was talking to Lois or I don't know, Batman, maybe the police commissioner who is the lead human protagonist in the story, talks about how killing Bad Guy X may be the only option.
Clark protests, and suggests that there has to be another way, any other way. After side-eying Superman for a moment, they agree that maybe, just maybe there could be another option, and then they talk with Clark. Someone who has experience with PTSD, or who has killed in the field, to have a brief conversation with him, and help him out.
And then they find a way to do things without killing anyone, but Superman has to sacrifice himself in some way in order to save the world again. Because if they're going to kill Superman (and they totally should!), it probably has to be in the second film. I'd love it if they killed him off in a third Superman, and then brought him back for a Justice League film, but I'm super nervous they won't be able to pull that off.
Maybe just a Batman/Superman film. Yeah, that could work.
