A good if uneven read. With Johns now back at DC, this book acts unexpectedly as a sequel to Doomsday Clock, which will impress and infuriate readers in equal measure. Without a knowledge of both Flashpoint and Doomsday Clock continuity (and probably even some New 52 work), it may be a hard read, even though Johns, Adams and Sheridan do good work to make it accessible. So much is unresolved for the Flashpoint universe that it feels like the JSA book won't be able to contain all the threads left open, and it's frustrating yet again for future events to be named without any certainty if Johns will ever get to them.

The art is also uneven - Xermanico and Janin are like chalk and cheese - both excel at what they do best, but they don't really mesh well here, and there's no balance between their respective arc. It's a fun time for fans of Johns' timey wimey schtick, although deeply self referential, and without much knowledge of the history involved may be somewhat disposable. In balance I found it quite likeable, and the writers did good work at fixing post-Doomsday Clock inconsistencies, most notably finally elevating Thomas Wayne into a hero on a par with his son.
