I don't read comics and have no emotional investment in Hellboy. That being said, I had a grudging affection for Hellboy 1, mostly due to my love of Ron Perlman's ridiculous face, and Frasier's brother that was that fish man or whatever he was.
I do REALLY want to see Hellboy 2, however, just to see some crazy-ass Giullermo Del Toro monsters.
