First, the appeal of Superman is his heart more than his strength. There’s one comic where he fights a giant robot and stops a runaway train, but the scene everyone remembers is when he talked someone down from the edge of a building.

Second, Superman may be invincible, but Lois Lane isn’t. It’s easy to defeat a villain, but much harder to defeat them while also keeping Lois safe. And she actively invites danger, so it’s always tricky keeping her safe.

Third, not every problem can be punched. Luthor’s greatest weapon against Superman isn’t kryptonite; it’s Public Relations. You can punch a monster, but that won’t help you stop a smear campaign.

I’m a big fan of Supes myself, but it depends on who’s writing him and what the goal is.

He is at his best when it’s a problem he can’t punch away, it’s about courage, and honor of defending others. Superman without powers is still the same stand up powerful character, that is crux of what makes him interesting.

Yeah, I don’t think that it’s a fantastic recipe for a character. The powers restrict the plots.

I think that less-potent powers tend to make for better story.

A lot of fictional series in various formats – not just comic books – make characters or events more-important or more-powerful over the course of the series, to top each previous episode, and I think that the plots tend to become increasingly constrained late in a lot of series.

it’s his ideals make him interesting, his nemesis litterally is an evil billonaire

It’s stupid because you don’t understand it? Aeems like you are the dumb one then.
