I haven't read it, yet, myself. I'll wait for the inevitable trade; IDW is good for that. BUT, I know over at the Chris' ISB (http://www.the-isb.com/), a term was coined:
Rucka is just straight up "Brubakering". That's sells it for me, right there. I've been hoping for Rucka to get back to his own independent stuff for awhile, because it feels like his superhero stuff isn't QUITE as good, sometimes. Though I haven't been reading his Batwoman (again, trade). I wasn't crazy about the Crime Bible mini-series, but I LOVED his runs on Detective Comics, Adv. of Superman and Wonder Woman.
