Just stop. This is not a matter of a publisher trying something new and purists acting petulantly. Hellblazer has for three hundred issues represented a showcase for adult horror and fantasy. It's been cancelled for no reason other than financial concerns, to be replaced by a book that fits in with whatever Warner Bros considers to qualify as an all ages audience for superheroes. If both were going to be published, a degree of respect for readers would be manifest.
DC Warners has made it expressly clear that its comics are, in fact, just for kids now. I have no interest in the priorities of accountants. I'm here for storytelling.
