A film i found on Netflix which came out in 2010, this is a very good flick for anyone who likes movies that are dark and kind of insane. The film seems to be very simple for the first twenty minutes or so, and terribly straight forward, but as it goes on the seemingly normal unravels into a psychological game of cat and mouse between the two leads. David Hyde Pierce does an excellent job in the film and does deserve more credit for his work.
I hate to say more about this film and spoil it, so please trust me and go watch it, its short, 90 minutes, and well worth your time.
