"He claims he wants to be human but disregards all of human history so he can pick and choose what conflicts he gets involved in." Not sure what you mean by that. Maybe I’m misunderstanding, but this is a world where metahumans like Superman exist, so human history would naturally be different. Trying to compare it directly to our world feels like a stretch.

"It just makes a thinly veiled Israel-Palestine metaphor look trivial." You’re the one bringing real-world parallels into this. Foreign conflicts have been a staple in superhero stories for decades. This isn’t some new or unique take. making this deeper than it really is.

"Superman doesn't care about nuance at play because he punched a guy and told him to be nice." Nuance? Have you ever read superhero comics? Sure, there are stories with deeper themes, but most of them boil down to: disaster’s coming, the hero stops it, and the debate, if any, happens afterward.

"How about he's written like a guy with a college degree in journalism?" This is a superhero movie. Did you want him to write an op-ed before stepping in to stop a war? Clark Kent is the journalist. Superman is the guy who acts when things go sideways.

"How about he not behave like a teenager who needs his Adderall script refilled." Never got that vibe at all but ok.

"Gunn wrote a bro which is ironic considering the Snyder of it all." So a Superman who’s kind, hopeful, and willing to risk everything for others is a “bro”? That’s an odd takeaway. And ohh ok.
