I'm of two minds on this volume. The truly horrific increase was awesome, and I loved how utterly fucked the whole town was. 
 And then, I also really enjoyed the last issue. These are two different likes. I have to separate them for my own enjoyment. 
 I would have been perfectly happy with it ending on number 19. It was dark, crazy, and had that last little lilt of joy in the very last frame. So sweet in an utterly horrific way. 
 And then number 20 comes around and turns it all into a (view spoiler)[dream sequence (hide spoiler)]? For Shame! No. No. 
 Well, that's all fine and dandy in the big view of things... but what really chaps my hide is that number 20 was actually awesome all by itself! It spoke to me on a whole new level and freaked me out all over again. I want to make it an alternate reality special. That would be very nice. 
 Alas. 
 Still, my enjoyment of all this wacked-out horror extravaganza is not lessened. Not much, anyway. It was CRAAAAZZZZYYYYYY good.

 Gotta pick up more of Junji Ito asap. :)
