The bad reviews are written by people who only know Hellboy as the first 2/3 films. If you're into the comics/graphic novels then this is a solid watch. Yeah, the acting has it's moments and the CGI isn't the best but it wouldn't be with a small budget. The score is 10/10 for me, similarly creepy disjointed string plucks they had in those early X Files episodes. Absolutely nowhere near as awful as people have (unfairly) made it out to be.
