So much Mignola stuff come out every month with him as writer or cover artist, I missed this when it came out 2 weeks ago. A very classic Hellboy story - atmospheric, easy to follow, and no convoluted mythology to wade through.
I'm kind of hoping this goes down like 'Transformers the Movie' - a shit load of classic heroes get killed, new heroes come out of the woodwork, and the story continues in the far-flung-future of 2005. That way, the Ultimate universe will separate more from the 616. Also: robots.
