Having never read but a few Hellboy comics, I had no preconceived notions on how Hellboy should be portrayed. What I got was a swaggeringly cool superhero that acts like a regular Joe, and fights a supernatural world of baddies.
Hellboy is very at home in this world. He himself is a creature of the underworld who has aligned himself with the fragile world of the humans. His assortment of allies are fleshed out and dimensional. Watching Hellboy: Sword of Storms feels like a piece of a greater movie without making the casual viewer fell left-out.
Thoroughly enjoyable for all fans of superheros, and kick-butt cartoons everywhere.
