This Hulk arc and ATLANTIS CHRONICLES(a crime that's not in print) are the best things in comics I've read of his. Tying the Hulk into childhood abuse fit perfectly in with why the green Hulk acts and thinks like a small, angry child. It violated absolutely nothing in the past and in fact solidified the character and opened more options. I wouldn't say it's quite as important a retrofit as Alan Moore making Swamp Thing an elemental and never Alec Holland, but it's of a kind with it. Few writers are clever enough to do a change that both reformats the character but doesn't do damage and I respect that.
