It's a decent continuation of the Injustice 2 story. The previous story left off with tragedy, and in this one, things are developing towards something big, but whatever that is. It's left on the back burner for a few flashbacks.
Ra's al Ghul fills the vacuum left behind by the overthrown Regime of Superman. All the while, Black Adam's welcoming of Kara Zor-El is a simple act of sanctuary as she begins to know more from another member of Superman's Regime with Damian Wayne, ending up with a mission to rescue Wonder Woman. With Superman imprisoned, Wonder Woman follows as well. Judged by her people, she is imprisoned for her actions in the five years she was a member of the Regime. But the story essentially ends here as flashbacks to several characters from the Flash, Grodd, Harley Quinn, Batman, Plastic Man, Wonder Woman, and remnants of the Suicide Squad and Harley's Insurgency.
This collection brought things down a peg for me. The flashbacks, I presume, come from the annual to get a glimpse of how things will develop in later collections, but it feels somewhat of a letdown. It was nice seeing Flash attempt to reform himself. I did find it cool that they introduced Dex-Starr in this version of the DC Universe. I also like how they worked this version of Wonder Woman in a way that referenced the DCEU Wonder Woman movie. I did feel sad about how they worked Harley's Insurgency, but they got to show how bad the villains got to be. Overall, this was okay but not as great as the previous chapters.
