Historically, these approaches haven't really proven to be any more successful than any other interpretation. Hell, since the "Clark first" mentality set in, the character hasn't equaled his previous levels of popularity. Even MoS got complaints because Clark made too many (human) mistakes and had too many (human) doubts and concerns. Besides, people expect Superman to be that bigger-than-life character; finding out he's just a regular good ol' boy would be akin to finding out that jesus couldn't pay his rent and cheated on his girlfriend. Underwhelming and disappointing. People dont *want* Superman to be a regular person, they want him to be awe-inspiring. Not that Superman has ever tried to be "god-like" in anything, but that's what people want and expect.
Besides, Clark is someone you emphasize with in an abstract way. He doesnt have the exact same problems we do, but the problems he does have are problems we can understand because, at the root, they're the same as our's. We struggle with paying the bills, Clark struggles with keeping the Fortress secure and stable (the ice caps are melting after all ). We struggle with cancelling dates because we got called into work, Clark struggles with cancelling dates because a nuke has been shot at New York. That's as close to "relatable" as Superman should get.
That's not a problem in the least. Plenty of his rogues gallery are more powerful, or equally powerful. The problem here is that the old movies and shows relied on those "short cut" weaknesses too much (budgets, I know) and now the general audience doesn't realize that most of the people Clark fights are just as dangerous as he is. The only challenge here is scripting the fights to be as engaging as possible, and MoS succeeded in that easily. If Snyder could do it so can other directors.b) create exciting fights that stretch Superman to his limits,
That can be done regardless of power level. Hell, Clark had good moments in JL with his team mates and that film was awful.c) creating interesting and personal team-up battles and relationships with his fellow Justice League members.
People already expect Clark to be space jesus. Not giving them what they want is a gamble. Maybe it'd pay off......but it seems to me there are better, safer, more profitable ways to be subversive and play against expectations.After that, then you can start easing in the "Superman is the best guy ever" interpretation because then general audiences will be more interested in multiple incarnations of the character in the same way Spider-Man and Batman have multiple interpretations in media.
