“ If you want a Superman movie done right, watch the Captain America films”.
Superman’s not human. Superman isn’t a government experiment. Superman wasn’t lost at sea and frozen for over 70 years. Superman’s love interest isn’t being forced out of the narrative once she’s done something useful for him. Superman didn’t run away when his universe’s public said he needed to answer for some of the damage he caused; he came fully prepared to argue his case. Superman is shown saving people in situations where he is the only one that could do so; replacing him with a super soldier results in all the people in those situations ending up dead. Superman doesn’t go on covert missions for the government; nothing he does is covert.
Clark Kent wasn’t a boy from Brooklyn who had to stand up for himself against bullies, Clark was a boy in Kansas with powers he was struggling to understand and control. He was a boy who could have destroyed any bully that got in his way, but his parents raised him better than that. Clark’s parents are present to give insight into how he grew up and why he feels the way he feels about his powers. Clark Kent was saving people before he put on the “S”, whether it be the kids on a bus, the workers on an oil rig, or the countless others Lois tracked down to figure out who Clark was.
They’re not the same character and they’re not supposed to be. Their cinematic versions are also different from their comic interpretations, so the courtesy of insisting that Superman is less of a superman because he doesn’t follow the comics completely should be extended to the mcu’s Captain America. This constant desire to see a Superman movie done like the Captain America ones ignores what the role each character plays in his own universe, as well as ignoring the genre of films that each character fits into: Superman is not a military asset/government personnel, and Cap. America is not an alien trying to find his place on Earth.
If your idea of Superman is a human-turned-super soldier that punches people for the government, then go watch the Captain America films. They’re enjoyable, and I won’t stop you, but I will say that they are not what Superman movies should be like.
