It just premiered here, and I went to see it. Not bad, not great either. A lot of action movie clichés. I don't want to say Stephen Sommers, but... room for improvement. Not on Ron Perlman of course.

Best casting decision ever.
I'm thinking I would've judged this more highly if I'd actually read a Hellboy comic, similar to how I would've been more critical of Spider-Man 1 if I'd never read those comics.
Still, a good time was had.
