I haven't noticed any disrespect either.
Let me first start by saying that the Superman created in this DCEU isn't perfect and he doesn't live up to the
"can do no wrong, smiling in every possible situation" status of what 'The Big Blue Boyscott' stigma has done to the character over time. I love the Big Blue Boyscout. I adore that version and I get that version.
But for an appetizer, I always, as a huge fan, asked for this type of flawed Superman that is both mentally confused and dissatisfied with the answers he is getting from the majority of existence as to why he is here and what purpose does he serve? I love this flaw and arc Man of Steel created and how it continues in Batman V Superman.
He's NOT the nostalgic; classic Superman fans all over the world, myself included, fell in love with...but ironically, I have instantly fell in love with this Superman for all the reasons on what classic Superman wasn't.
Am I fully content at where Snyder's Superman stands at the moment? I can't say yes, but that's the exact part that makes me a fan of this version. I'm totally ready to stand beside him on this journey, flaws and mistakes and all, to receive the ultimate payoff I'm almost certain I'll get that brings Superman full circle and not so 'one-note.'
Quite frankly, fans want things all NOW "or else" but for me? I would have felt dishonored, especially a fan of Man of Steel, if Superman's characterization would have immediately went to to iconic; classic status. That would have been lazy and a confession, to me, that the writers and director of this film agree that Superman is boring and that there is nothing else left for him to do.
Though this Superman is "questionable" and "full of flaws that makes questionable mistakes" IMO, this is the most respect the character has seen in some time. The story begs you to realize that all of those mean things said about Superman are simply.....wrong. We need to believe in him.
