Why do I like the two-issue JLA/Hitman special?
Because it stars a dead DC character who has stayed dead, and it makes you feel like his death is a loss.
Because the JLA members are five different characters, and not the author's voice lettered into five different speech balloons.
And because it's one of the best things you'll ever read about Superman (It's also the best Wonder Woman currently on the stands. The three page dialogue with her and Superman nails them both. Compare it to Judd Winick's Superman/Wonder Woman scene in the Black Canary/Green Arrow Wedding Special, and try not to weep for what passes as "writing" in the current DCVerse. Go ahead, try. I dare you. )
Like any other talented mortal, Garth Ennis fluctuates between writing and typing. (Preacher? Writing. Wormwood? Typing. The Boys? A little of both.) Put this one firmly in the Writing pile. Put it right up there with Hitman #34.
