Ya know, I keep hearing about turf wars at DC between Vertigo and main DC, and to a certain extent I understand them. Vertigo is trying to be a step above the rest, keep a certain creative vision and tell stories of a certain quality.
But seeing that Kevin Smith, of all people is allowed to play in the sandbox when other, better writers weren't (That Captain Atom arc with Death, or Johns when he wanted to use the Sandman name in JSA) really makes me think it's less about quality and more about a stick up their ass.
