Great review. I've been catching up with new Hellboy the past year (after getting tired of the same 4 trades the library carried) and I've read almost everything save the Africa issues, HB Animated and every BPRD series save the first. Enjoying Corben's past Mexico one-shot, I'm glad to return to a fun, silly HB yarn after The Fury.
I just might wait for this one secondhand though, it sounds like a light read that's more fit for two $4 issues than a $15 hardcover. But that's just me.
