Now this seriously looks scary. It seems to be about this crazy genius psychopath guy in a gremlin mask who kidnaps people, and locks them in a room with their arm or leg shackled to the wall with a saw. And in the commercial, it seems to hint at how the crazy gremlin mask guy wants to see if they'll cut their leg/arm off.

I am so not seeing this movie, but it looks very scary. Did you see this commercial? What do you think of this movie?
