That's poor reasoning. Because what you actually said was, "Why read something complex when you can get something simple," and I'm fairly certain you didn't want to mean that.
Ehh. There are levels of need when it comes to complexity. Comic books are just reaching soap opera proportions of "It wasn't him! It was his evil twin!" And I doubt anyone is going to argue in favor of the "complexity" of soap opera plots.
The difference between comic books and oral traditions is that comic books are permanent artifacts (relatively speaking). The result is, you can't just change the status quo and have that new status quo to tell stories with. Because the old stories are still there when you tell new stories, people feel it necessary to ask the question, "but how did it get from A to B?"
So you have to tell these massive stories explaining away the change in status quo, and it takes so long and is usually so mind-numbingly stupid that by the time you're done setting up the new status quo, they've moved you on to another book before you can even tell any
actual stories with it. So the only stories you get are stories about status quo changing, and while that's fun once in a while, it shouldn't make up the bulk of your storytelling.
If they want Bruce Wayne to be alive, they could just have Bruce Wane be alive and tell stories with a living Bruce Wayne. But no, in order to read that story you have to learn all about the Lazarus Pit and Nekron and the Black Lantern Corps and Omega Sanction and
why do I want to wade through all this **** just to get a story about a dude in a cape fighting crime?
As for Smallville, here's the thing: no one
new is actually coming into the show as of season 10. Because at this point it's just too inbred and complicated for anyone new to want to touch that. With TV, most of the time you have your audience set up by season 3 or so, and after that you're just doing anything you can to hold onto them until you either end the story or the show ceases to become profitable. Comics are the same way; they've just been in the "hold onto the established audience" mode for decades-- but since they'll never let the stories end, it's just going to be a slow, sad decline of quality-cutting and poorly planned "events" until that little profit line finally dips into the red.
