The Hellboy comics are some of the best things ever made. Rooted in folklore and feeding off the weirdness of old school Catholicism, they are, in essence, stories about a big dude who can take a lot of punishment while fighting monsters. That is what we call a "winning formula," and it would take a lot of work to fuck that up. Luckily, creature master Del Toro and his movie do not fuck that up.
