Meh I find it hella interesting. He can still be a hero too, and it doesn't negate the sci fi aspect at all (degrasse tyson even says how Superman challenges our belief that we're alone and superior in the universe). I always thought the Thor stuff in mcu missed out on a cool angle because of how blatantly they ignored such a plot point (Thor even has a basis in a real world extinct religion too)
Superman doesn't challenge my beliefs you can still believe in a religion and believe that we aren't the only sentient beings in the universe.
As for Superman I just want a straight forward film with a dude who's a reporter who happens to use his powers to do the right thing. DC can keep their movie if they want to keep pushing the god angle.
