I think they covered Superman as supreme ruler (kind of) in the comics. I read an excerpt or description in some anthology or something (sorry, this such a bad description blush ) and it ends with Kansas (yes, that would include his parent's farm and his hometown) being destroyed during Doomsday or a nuclear war or something. And because he couldn't save Kansas he renounces his supreme leader powers and goes back to being guilt-ridden Clark.

** SPOILERS ** Lex in Smallville show also hints at this same plot at the end of S3, when he suggests that the man who stops this all-powerful being (who is foretold by the local Indian tribe) maybe not the bad guy (as Lex or his father is foretold to be) but maybe the good guy. It certainly gives a Clark wary about his foretold future something to think about, especially their friendship.

I complete agree with #1 the retelling of the Star Wars prequels, though. clap (I hated... well, I was going to say #3 but actually all three of them).
