I don't like the angle the story itself is trying to sell on him but I do think the reactions of the characters inside the story are realistic to what would happen to him in the real word.
Lex Luthor hates him because of his own internalized issues, using him as a scapegoat he can pin blame on. Pretending he hates him due to some higher purpose.
Bruce hates Superman because he doesn't understand him, and people fear what they don't understand. (and in this universe metas became common after Superman appeared so this Batman has no experience with superpowered beings, he didn't slowly increase the powerlevel of the powered being around him, he went from 0 to a 100, and that is scary)
The people who he has saved and cared for love him because they've seen him, they know him.
The people that hate him tend to be people in power or those affected by Black Zero.
He didn't get that much time to make the world know him, he was Superman for like 2 years only, compared to the 20+ he has in the comics.
He is this powerful being that sprung out of knowhere, that is bound to make people afraid, and no ones likes being afraid so they hate.
I think the most realistic part of the movie is the tv scene where people are sitting down and talking about weather he should be allowed to roam free or not.
As if it is moral to deny a sentient being freedom/ autonomy.
Because as much as it sucks to think about it is what would most likely happen if a superman appeared.
People say snyder superman is too angry or gloomy but who the fuck wouldn't if they were subject to hearing people treating them like an object and hating him?
I find the polar opposite depictions of Jonathan in these stories incredibly fascinating.
MOS Jonathan shields and separates Clark from anything related his heritage, including things like his ship and powers. Encouraging suppresion and caution in Clark.
Actively telling Clark to hide his powers and never use them, scolding him whenever he used them. He is a man terrified of the world taking his son away from him, specially knowing he has no real way of protecting Clark from anything that may seek to harm him. So he encourages him to hide himself and avoid drawing any attention.
He is a more jaded and cynical man, immediately assuming the world would attack and try to kill his son (he ended up being right, which is its own can of worms), would try to rip his miracle child, his star baby away from him.
He only sees a world that would harm the child he so desperately seeks to protect, that child he loves more than anything.
MAWS Jonathan is the complete opposite of his MOS counterpart. He is the one that encouraged Clark to discover himself, to make contact with the ship, to practice his use and control of his powers, even turning that into a game a young Clark could enjoy.
He is aware of the shock Clark´s existence will create but in the end he has faith in humanity seeing Clark for what he truly is, someone who just wants to help others.
He is more optimistic and cheerful, thinking of the best and encouraging other people to do so too.
In MAWS, Martha is the one who is the one who wants to keep Clark away from anything alien, the one that clings to him and wants to keep him hidden.
While Jonathan is cheerful over Clark deciding to go public and help people, Martha is the one that is slightly reluctant (though not to MOS Jonathan´s level, like letting yourself get killed by a tornado because you don´t want your son to expose himself is extreme though somewhat understandable) to let him go, though she eventually gets on board and creates his trunks.
This dicotomy is reflected on Clark´s abilities.
Flight is one of his most characteristic abilities and it often serves as a metaphor for Clark feeling free and accepted, it comes in moments where Clark learns to love and accept himself.
So it is interesting to see how in MAWS it is one of the first he obtains while in MOS it is one of the last ones. Showing the difference in how their settings and enviroments reacted to them.
MAWS is honestly amazing and I am incredibly glad we got this adaptation of the Superman mythos. It is so unique and refreshing. I can´t wait for season 3.
Regardless of its flaws I genuinely love MOS and its depiction of the Kent family. Its different from what we are used to in comics and tv shows, but it offers a unique take on the Kents dealing with Clark´s powers. At the end the day Jonathan is just a father terrified someone will hurt his child and he won´t be able to protect him.
Anyways this ramble has lasted enough, love both pieces of media to bits.
