I had to scratch my head at
zombies. But the whole functioning well enough masked as humans was a nice twist and making it the result of Kanshuu "biology" patched up any potential holes. Seeing a group taking an active role in terms of dealing with the rebound was also nice. A slew of other dimensions to the infected crisis opened up as a result (rebound, volunteers, indifferent jinki holders, etc.). tl;dr Series is getting pretty damn awesome even when prior events were pretty damn awesome too.
