Honestly, I feel like both sides are kind of right on this one, in that I think people have largely made up their minds by now on whether Morrison is for them or not.
So that means that readers that like him might be willing to tolerate a level of indulgence or esoterica that they might not put up with from other writers. And readers who don’t like him might be quicker to jump on his weaknesses and try and point out that the emperor has no clothes.
I’m a Morrison fan but I don’t think everything he touches is gold (that recent Sideways annual was pretty poor, for example). What I have appreciated is that he’s branched out in a few interesting directions lately, with projects like Wonder Woman Earth One, his Heavy Metal output and Green Lantern all feeling quite different to one another.
