You know it is something i have been wondering, how would marvel handle Batman v superman and i can only imagine it would be more like that scene from the avengers when they are all initially fighting each other and then there is that moment of "oh maybe we should not do this before somebody dies" because you know, its written by people who do not say dumb fucking shit like... what was that dumb shit snider said why he had superman kill Zod so he understood it was bad to kill...
I mean even in the first movie there continues to be a lot of tension, they do not get along but they manage to work together and its actually what makes the most fun little moments.
I know you posted this a while ago, but I actually took that interpretation and me being just way too optimistic, I thought they would make something out of this. Like I know a lot of people were like "Superman killing someone is so fucking dumb" and I kind of looked at it at the time as kind of being an origin story kind of thing. Zod and the other kryptonians were the first time he had to deal with anything serious, before that he was just pulling a bus from a river and stopping and oil rig thing from falling on a helicopter. He didn't bother to practice with his abilities because his dumb ass dad was like "No, Clark, don't very fucking easily come save me from this tornado, people can't see your powers."
So I was like "Okay, he killed Zod, but he's inexperienced with his abilities and lacked a lot of options. Give me that grain of salt and lets hope the next movie builds on that experience."
Then just...fucking nope. They leave no time to have him dwell on having killed the last survivors of his destroyed homeworld, and he seems pretty over it anyway. He's too busy taking his journalism career seriously (ha) and dating. He never even took the time to learn to take off without breaking the fucking sound barrier, let alone practice ways to utilize his abilities non-lethally. That could have been done between movies, but nope. Snyder doesn't wanna do that I guess. Even though in the comics, we suspend our disbelief that he would have been able to zoom over to the warlord guy that had Louis and come to a controlled stop to disarm him or use his heat vision with enough precision to burn his hand or something. Hell, they could have even had a short slow motion sequence and shown him twisting in midair so his body broke through the wall instead of the normal human he just tackled at the speed of sound. But I imagine they didn't think movie goers would find it believable.
Except for ANY of them that have read a few comics. Which I would say you probably only need to read about four to have read more than Snyder.
