While some might label this movie torture porn, I would argue that it is not. Most films like Hostel or Saw do not offer a coherent story or subject matter. While I've enjoyed some recent horror, those films revel strictly in shock value and senseless carnage. Martyrs blurs that line and finds itself questioning age old themes of religion and the after life.
You've been warned. Only see this film if you can handle scenes of intense terror, violence, and brutality. If you are a fan of Funny Games, you'll enjoy elements of this. Personally, I highly enjoyed this bleak ride.
