Trailer, spoilers, questions (spoilers)
So the trailer and the description gives it all away so what's the point? A criminal breaks into the wrong house and is tortured by the home owner. Pretty much like Ghost Writer (aka Suffering Mans Charity) where the "bad guy" who is not all bad, is tied up and tortured for the whole film.
Is anyone really interested in a plot like this? I hope there is a lot more to it, more than "there are crazy people in any given random house so watch out." Because really, if that's it, tell me once in the entire history of crime where something like this has happened in real life?
