Hostel movies: where is the truth?
The truth behind 'Hostel' has indeed its roots in the side-open spaces of Thai villages. Here, society is ruled by powerful, organized crime syndicates that, taking advantage of people’s poverty, lure the youngest away from their family with the promise of well-paid jobs. But what awaits them is a life of crime and abuse. They are usually thrown in arenas and forced to endure physical and mental abuse to please the psychotic gambles of rich people, who are willing to pay exorbitant amounts of money to see people kill each other.
