Special effects really carry the film. The attention to detail and a somewhat complex plot leave you wanting more. The only drawbacks are: 1)Prince Nuada's over-extended training and fight sequences... We get it. 2)The overexposure of Hellboy's weird yellow eyes, instead of mostly shadowed in the first film. I understand that action is key to keeping short attention spans focused, but it's an unfortunate trend that sacrifices character development and general depth in key plot elements. I bought this sequel to complete the set, because the first one made me want anything related.
