What they got right: The story ends well, and Terra's part (and her interesting friendship with Power Girl) feels right. The art is amazing as always. If it feels like I'm fighting to put something here, I actually am.
What they got wrong: I still can't get the taste of last issue out of my head. Had the writers not went for that disturbing origin story last issue, this could have easily fit in this issue, without all the padding. Extra time this issue could have been devoted to learning if Donna has a happy reunion with her baby or more of what the JSA is doing down below during the crisis. Instead we get bloody monkey bestiality and monkey brains. Nothing this issue changes the fact that that happened!
Recommendation: My comic collection is becoming unmanageable, and with my funds limited, I really have to be picky about what I get. Sadly, while the writers do a good job with Power Girl, they mess up so many other points, that I don't see me picking up this series. This arc was the pilot, and if you ask me the plane crashed.
