A decent enough storyline throughout much of the book, but Johns reminds us once again, that he cannot POSSIBLY write a story ALL the way through without killing something - in this case, the ORIGINAL Justice Society of America.
Waay back in the 1960s, a half-a-hundred years ago and more, DC brought BACK the Justice Society, in a way nobody had anticipated: They were inhabitants of another Earth, a scientifically plausible explanation that covered all the bases. Why Superman, Batman, Wonder Woman and their sidekicks had not aged, why there were different Flashes, Green Lanterns, Hawkmen, Atoms, all with slightly to vastly different powers, how one hero could be inspired by a comic book he himself had read about another hero, to take up his mantle, and, of course the absence of certain heroes from mainstream continuity who nonetheless managed occasional adventures.
Then Marv Wolfman's Folly happened, because Jenette Kahn, in her infinite senility, had decided that it would be an official GREAT idea to wipe out half of the heroes in their lineup, and WE got landed with, well, Giffen and Johns. PROBLEM: Wolfman hadn't managed to actually murder anyone from Earth-2. Solution: Johns and Giffen got to start murdering them and shitting all over their memories, OVER AND OVER AGAIN. The final scenes in the last pages of this collection bear this out, and THAT'S why this gets NO stars from me.
