I just think that maybe comic book movies don't have to be realistic. The MCU goes for nice blend of realistic and pure fantasy with most of the realism coming from how people react to things, the best being all the Avengers becoming celebrities with the Hulk being the funniest. Seeing horrific violence that intentionally references a tragedy where actual people died in a Superman film just seems wrong. Then saying his symbol means hope just makes it worse, I don't feel hope from that. Superman seems like a danger to everyone. If you're going for hope, make the audience believe in him and it fails at that. I don't think Sydner understands Superman at all and tried to turn him into something he wasn't in order to tell the story he wanted to tell.
