Ennis and McCrea, like Alan Moore and Matt Wagner before them, make Etrigan a barely controlled monster. They make the human Etrigan shares a body with, Jason Blood, into a whiny incompetent. They make the various supporting characters into buffoons and punchlines. So it goes. It all works because Ennis and McCrea are really good at ultraviolent horror comedy. It also works because they introduce their super-powered hitman character (cleverly dubbed Hitman) in the course of these issues. Hitman would get his own series. As is pretty much always the case with Ennis, he'd seem a lot more comfortable and a lot less scabrous writing his own character.
The standout story arc here sees Ennis and McCrea bring back DC's venerable weird war series The Haunted Tank. The cognitive dissonance generated by a story of an American tank haunted by a Confederate general taking on a bunch of resurrected, supernatural Nazis with the help of a nihilistic Demon is a wee bit mind-blowing. Perhaps never moreso than in a scene in which the Demon explains to the Nazis why he finds them repugnant. It's crazy fun, and it allows Ennis to himself resurrect some of the ridiculous maneuvers the dinky little Haunted Tank once performed so as to defeat seemingly endless hordes of vastly superior Nazi machinery.
Is this Kirbyesque? No. And Ennis' decision to have Etrigan speak in rhymes all the time -- based on a long-standing, DC-wide misreading of Kirby's original Etrigan , who only occasionally spoke in rhyme -- can make for some truly godawful writing at points. But, you know, Nazi zombies in tanks! Recommended.
