There's a great story by Alan Moore (cranky British genius who wrote some of the best comics ever to be made into terrible movies) called "Promethea". Really, it's three years worth of stories leading up to the end of the world. Everybody knows the end of the world is coming, signs and portents are everywhere, that whole thing. Folks go a little nuts, get in fights, try to settle old grudges and then, realizing it's all in vain, they give up the struggle, figure out none of it was that important, hug it out, band together, and wait for the end. The lights go out.
Then they come back on again.
Either no one has died or everyone has, but they're in exactly the same place. But everything is different because what ended was that state of mind, that point in history and all the bullshit that went with it. And now everyone gets a fresh start with new eyes and an open heart.
If the world has to end, I vote for that one.
