It's not bad.
James Purefoy is a great British talent (from my Cdo's home base), brilliant in several movies (initially as a minor role) - A Knight's Tale), Solomon Kane, etc. I believe you yanks can't see it, or something or other, I'd definitely advocate a way of watching it, one of the best fantasy/horror films of the last few years.
And the other actors, Jason Flemyng, Jamie Foreman, and one of the worlds best actors, Brian Cox make it fucking stellar.
Very underated, but I think that's because it has the tagline of being similar to Zack Snyder's 300 saw many people think *fuck it*.
Oh an Bree Condon? *mmnmnmnmnhhh*
