I'm not saying the specific themes of "soldier who fought in war has difficulties acclimating" (and, having actually seen Winter Soldier, I would argue that it handled that theme cartoonishly, but that's neither here nor there). I was more referring to the general theme of a highly competent person whose skills are not suited to the world they now occupy. It's not a perfectly straight 1:1 analogy, but just as Rambo was in charge of million dollar equipment over there and over here can't even get a job parking cars, so too is Superman capable of fighting off galactic threats but can't treat depression or fix world hunger. He can stop murders, but he lives in Metropolis - even though it's no Gotham, crime is still abundant enough in a city of 11 million people. He can't stop every mugging, every assault, every extortion. And hey,
he can even stop a mugging, but he can't stop the underlying cause.
...
Seriously. If SMBC can come up with interesting
moral and
logistical issues for Superman (albeit veering sharply into the absurd with its outcomes, because it's a humor-based format), then Hollywood with all its resources sure as hell can.
