Superman is only a boring protagonist with an unimaginative director and writer. The thing that is boring is having one-dimensional villains that can only try to fistfight him (like Doomsday, a villain created solely for the Death of Superman arc and has done nothing of note since). Superman isn’t a Dragonball character, his sole purpose in the story isn’t to be guy that beats up the bad guy. If there was one good point of the JL movie, it was that the way to beat Supes is to distract him by giving him someone else to save, because Superman will ALWAYS prioritize saving people over beating up the bad guy. Superman is supposed to be the example of what a hopeful, helpful being could be when given godlike powers and NOT wanting to abuse them looks like. Unlike Spider-Man, whose struggle to balance life and crimefighting is part of his narrative, Superman does all of this because being a hero is who and what he is, and he gives everything he has to do that.

But I overall think you and I are on the same page: DC shit the bed.
