Hostel.
I personally have no idea why I rented it because it was tedious and I never really understood enjoyed the horror genre.

The Road To Guantanamo.
Good depiction based on the tiption three. Shows the treatment that most, if not all the detainees are going through. It also made me feel ashamed to be apart of humanity.
