Ambitious is an understatement describing Geoff Johns' Justice Society of America Vol. 1: The New Golden Age. Johns is all over DC history here, from All-Star Squadron to Infinity Inc., “Batman: Year One” to the Legion of Super-Heroes, plus Doomsday Clock and Flashpoint Beyond. It’s a lot, confusing at first, though it mostly settles down by the end.
For as much as the covers of the individual issues show the Justice Society in battle, they are less consistently in the foreground than one might expect, in favor of hero-from-the-near-future Huntress Helena Wayne. There’s a sequence in which the Justice Society is wholly absent and the action focuses on Deadman, Detective Chimp, and Madame Xanadu. That is, the topic du jour might be the Justice Society, but let us not kid; the amount of Batman here alone suggests Justice Society as a vehicle for Johns to write a whole DC Universe book (which, come to think of it, is a wonder no one has tried before).
