Meehl, you'd be easier to take seriously without that dopey sig.
I do agree that Delano's John was smaller scale and considerably lucky to note end up skinned somewhere but still alive.
The Horrorist and Bad Blood go full on for the detritus-John, the mess that's left but thank all the gods you can muster it wasn't that golden boy twin instead.
Ennis had to go somewhere with the character, so he upped his heroism and capability foremost, and his charm a bit, secondly. But, that's okeh, punk was dying off anyway. A facelift was good, and a facelift that ages him as well, even better.
Who did the reality TV in Hell story? Was that Rankin?
I think what I most disliked about Azzarello's take was that John seemed shorn of a lot of the John Constantine that had aggregated over the course of the series and while I mind that less with Spider-Man or Batman or whomever, with John it did seem, at the time, a dehumanizing, a de-Johning. In retrospect, it's fairly tight for what it is, and the most anyone's ever tried to obscure their own personal ethics and politics in a Constantine story/run ever. (Maybe I'll change my mind again if I reread it in ten years.)
