man, black hammer has really exploded. i keep thinking its been like a couple miniseries but they've hellboy'd that entire series now. I meant to buy the first trade and now i have an entire franchise to catch up on. i wonder if dark horse is going to do those nice softcover omnis like they did for hellboy stuff.
i'm sure jeff will do something like that. its kind of crazy that it even comes out from DH since he controls all of it (from my understanding). i've really enjoyed nearly his entire output ever since way back when he was just getting into monthly comics after ESSEX COUNTY and would frequent a msg board that i was a mod on. comparing the guy i used to chat with and the guy in recent interviews, he seems to have always had an insane work ethic and is always super far ahead on stuff so him having that kind of personality i'm willing to bet BH has literally dozens of books being plotted/ created that we wont know about until like 2021
if you are just trying to enjoy the main book though, you honestly can read just that though. the others flesh out some cool bits and are good stories on their own, but i don't think youd be missing out on 'important' stuff
