^^^Interesting. Hadn't thought of that.
But the bottom line is that there can be lot of drama to the Superman character. The point is that despite his awesome powers he still has emotional vulnerabilities. He also has people that he cares about. Through these elements, he can still be hurt. A great story doesn't have to be about a physical fight.
I quite agree. The best stories, or points within a Superman story are about where he has to decide whether to use his powers or not followed by the consequences of the decision. The stories about the consequences are far more engaging than what the super powers can do in and of themselves.
