Ex Machina #31 reviewed elsewhere

I have not yet received my copy of Ex Machina #31, in which Mayor Mitchell Hundred meets the Pope. But Don McPherson has, and he reviews it at Eye on Comics:

Really, this story arc is about the fundamental differences between the secular and spiritual worlds and how they hide common ground. Serving as a symbol of that approach to the storytelling is the story arc’s title — “Ex Cathedra” — which is a religious play on the title of this series; it’s different but similar.
