Robinson's Earth 2 has long had a pair of problems: it's too decompressed and it's too fragmented. These problems don't go together well, because they result in an overall story where pretty much nothing is happening because each fragment of the story only gets a tiny bit of movement. That's sort of still going on here, in a Hawkgirl story that doesn't go anywhere, but fortunately the rest of the comic has reached a big climax which helps it to recover some of its momentum. 
 With that said, I was somewhat surprised by this comic's sharp right-hand turn. In the first two volumes, it had very much been Ultimate JSA, but here it seems to moving more toward a sort of post-apocalyptic super worldview of the type seen in comics like Injustice: Gods Among Us and Kingdom Come. It's not a bad direction, but it's a surprise, with the result that this comic is less and less about the JSA and more and more about ... apocalyptic showdowns. 
 Sadly, this book doesn't have an ending, as is too often the case in Nu52 volumes. However, it was quite an enjoyable read getting there. 
 I was pretty unhappy to hear that Robinson was forced off the title after this issue; it's, in fact, what made me decide to read it from the library instead of buying it myself. But Tom Taylor seems like the perfect person to take over given his own work on ... Injustice: Gods Among Us. As long as this one can remain fresh and different from his other work.
