The sad thing about this isn't just that Wolverine couldn't talk without a face, or been able to make more than a few unintelligible sounds (and, you know, you'd think that the writer who'd created Arseface would have been the first guy to pick up on that), or that his relentless monologuing is wildly out of character, or that Wolverine would have to have had the idiot ball surgically attached to him with adamantium staples in order to lose a fight to someone, even Frank Castle, who was using conventional weapons, something that any writer but Ennis, with his diamond-cutter boner for war comics and an equally-priapric hate-on for superheroes, could easily grasp.
No, the really, really sad thing about this is that Ennis is just recycling a very similar plot from the Hitman/Lobo one-shot, and in that book it was actually funny. (It helps that I don't like Lobo, and also that that comic featured Bueno Excelente in a wedding dress.) This issue is one of the stories that convinced me that Ennis was deliberately turning in scripts that were either warmed-over crap or abject gross-outs (i.e. the serial killer who liked to sleep under an enormous pile of rotting corpses) to have Punisher moved over to Max, so that he could kick loose of the mainstream MU.
