Now for comics and movies, they need to make him relevant for this century. Hasn't been since the 80s. Closest thing that has made him relevant recently is the Animated Series (TAS) and Smallville.
Problem is to many people he is just too boring. Google "most boring superhero" and Superman DOMINATES the list.
Here is what they should have done:
- Nerf his powers. Have electricity hurt him, as well as bullets.
- Give him a good villain. Too much Lex and Zod. What about Metallo, Brainiac, or even Bizarro?
- Give him some moral complexity. Have him kill a little more - be less of a boyscout. Enough of this "new aged Jesus" crap.
- A better disguise. The "glasses" thing was even ridiculous in 1978.
These are steps needed to make Superman relevant again
