Why didnt they just leave?
I am currently 2/3 of the way through the movie. They are both clearly not having a good time and some crazy *beep* is going down.
Why did neither of them bring up simply leaving? Perhaps drive to the nearest city and get a hotel room and vacation there for a few days?
Lets just stay at this house thats completely isolated, where my wife potentially got raped and something is shining a light through the windows all night.
