The Superman stuff is what takes me out. Snyder’s Superman is such a mess and the main reason why I end up disliking his films. It’s obvious that Snyder’s only interest in Superman is making him an antagonist. The “how do we make Superman interesting” answer is “make him evil” every time. It’s what he does every time, and even Suicide Squad works on the premise that the team exists in case Superman went bad.
And I think this works if he committed to it. But he doesn’t...at all. “What if Superman was hated like Spider-Man?” might actually make an interesting movie, but Snyder wants the audience to be skeptical of Clark while also making the in-universe population love him. But they don’t ever see a loveable Superman outside of the footage Joss Whedon shot.
If Snyder got his way, Clark would be a villain in 4/5 movies he was in. And in Man of Steel, Clark is only not the villain because he’s fighting three evil Supermen. Clark redeeming himself (even sacrificing himself) to make up for what happened in Metropolis would be really cool. Superman having to earn the people’s trust is a great premise. But Snyder doesn’t care about redeeming Superman because he doesn’t like Superman. I think Snyder thinks he’s boring. So he engineers ways for Superman to be the bad guy again and again.
If I were Snyder’s script doctor, I would do it this way
BvS - Mostly the same except a) Batman is the champion of the people (maybe even the government) instead of working for revenge. When he realizes Superman is good, he teams up with Clark b) Clark is working his butt off saving people and winning people over. He’s Chris Reeve Superman. He still dies
Justice League - The same except NO Superman. He’s dead. The League has to win without him.
Reign of the Supermen - Do a full movie of this. Four people emerge claiming to be Superman. Batman has to figure out who is who, knowing that they will need a Superman vs Darkseid. Cavill’s Superman comes back.
Justice League 2 - Darkseid shows up but Clark isn’t ready. Or sure of himself. Batman trains him. The League fails and Superman comes in to save the day (like in Justice League) but gets his butt kicked. Cliffhanger
Justice League 3 - If you want to do evil Superman, do it here. Clark is at his lowest and susceptible. But he overpowers it because he’s won everyone back. He’s the hero of Earth now. And United, they take Darkseid down.
Clark goes through a journey of redemption. He has to win over the people, he has to conquer death, he needs to prove to himself that he can, and he needs to destroy the bad guy.
