There's been protests. Christian groups are upset at a horror movie being released at Christmas. Although, seems none of them mentioned Apocalypto in their criticism. Hmmm, I wonder why?
Anyway, I haven't seen either and I'm not going to. I'm not a fan of horror movies myself other than the occasional James Whale or Hammer Classic. I am a fan of Miss Trachtenberg, who stars in Black Christmas, and have been ever since she mysteriously materialized as Buffy's sister. Seeing these pictures one can only be further impressed.
