I pretty much agree with all three of these. I'm not in love with Zola as a character or anything, but she's grown on me on re-reads. Ditto Lennox, Siracca, etc. I've come to appreciate them a lot more in light of Jason.
Rucka's best contributions during Rebirth were definitely Year One and Godwatch. They just filled in the blanks for the new history by telling good stories instead of drawing attention to the continuity changes. I still really like The Lies and The Truth (mainly all the scenes with Cheetah, whom Sharp draws wonderfully) but the present day stuff was the weaker half. I kind of wish the Rebirth one shot had just explains the basic setup of things going forward: the New 52 events still generally happened, but the Amazons had their technological advancements and didn't kill sailors anymore, and no male Amazons.
