Re: How would you make Superman Relevant?
He already is...
Superman is a fictional character that represents a fantasy we have about someone swooping in and saving us... from small crimes, from major natural disasters, and from our own complete incompetance as a human race.
I don't see how that is ever not going to be relevant.
The more important question is how you make Superman 'likeable'. Which I think has been the main problem.
Superman: Don't be afraid.
Lois: I'm not. Helicopters, danger, go, go, go! Then we'll talk.
