Best one I heard was that the world is in lockdown because someone almost reached the end of the flat earth, and so now nobody can travel or the secret of the flat earth would be exposed.
I'm same as you Sean. Never really been "into" comics, but like a good GN from time to time. The elite level shit like Watchmen. It's not all contained in one GN (I think it's 9) but have you got round to Preacher yet? That is similarly incredible.
