Ok, boomer?! I’m 35. This has saved me more than once. All Star Superman 2012.
...I'm going to throw my line in the sand: The depiction of Superman isn't the issue. Nor has it been an issue. It's a grounded take on the character, as it felt for MoS/BVS that he was trying to figure out..the good that he could do.
I think for JL, we aren't..going to see as many changes as people expect. Just, it being much more fleshed out and showcased; as there is small elements of comedy in both MoS/BvS, but it isn't supposed to take over a film's tone like how JL did.
The tone's I've gotten from the past are this:
Man of Steel tackles that of Clark Kent, discovering his powers and testing the initial boundaries, and is put to the breaking point because of Zod being a natural warrior, with more experience than that of Clark/Kal El. Once he snaps Zod's neck, Clark and Kal El begin to lose the innocence. And while they want to protect the planet they call home, the value of sacrifice is drilled in.
BvS, tackles on the ramifications of Superman's actions from MoS, and how it effects the DCEU's Earth in many ways. From that of Diana and Bruce stepping out to the shadows, to people like Lex wanting to test how people view Superman. And for Clark/Kal, it's about finding his place if he does belong on the planet that he has called home; especially as he gets kicked down multiple times for it.
I could see Justice League tackling on the subject of how Clark Kent and Superman's Death affects the universe properly; as for all intents..he is absurdly powerful. Powerful enough, to where Darkseid notices more easily.
