Yes, Morrison does come off as a jerk.
However, it's really DC editorial at fault. They need to either get Morrison to play ball or find out a way around that.
What's interesting is that, as I said upthread, the back-ups in
Action are awesome and fit in with what Grant is doing. A few months ago, it focused on Clark selling the farm, something that this month's issue referenced. The Steel backup also fit in quite well, narratively, with the main story.
So if Morrison worked with Sholly Fisch, why not with Perez? Editorial should have made sure of that.
Either way, I'm not a fan of having a book set in the past. Sooner or later, it'll end up contradicting something. It really hamstrings those writing books in the present.
