Off topic: I think you need to relax with all the thread making. Just concentrate on making one good thread instead of a bunch of random brain fart ones.
On topic: What's worth developing? Nothing. It's all screwed. We have superboy. We have real estate lex. We have Mommy Lois. We have useless Richard White, typical soap opera love triangle guy... it's screwed so badly there's no going back whether some want to admit it or not.
I'd like to see something happen to superman like what happened to batman but that's probably never going to happen since WB's really has no idea what it's doing. If there were a positive way to make things better, I'd say, have superboy just dissapear (it happens on tv shows all the time) start fresh like the last one didn't really happen. Make it vague history.
Have the next superman be more its own style away from donners. Use your imagination to come up with something really knock out brilliant! No more christ parallels, let the story focus on the coolness of being superman, having powers every man wishes he had. Don't make it an emo burden. That's not superman. That's batman.
