I would love it. No small part of my complete lack of interest in the MCU currently is that every single story revolves around huge, world-affecting problems. Smaller stakes can still be interesting and matter a lot.
ETA: Yeah, but the more down-to-earth aspects of superman are more relatable for more people, was my point.
And this is totally the problem (well, a problem). They can, and should, tell more stories focusing on the Clark Kent side. More human stories with problems that can be solved by being Superman but can be solved by being a good man. I agree that his superpowers can easily make him boring, and a good way to captlitalize on who he is would be to focus on who he is instead of what he is.
