A loose adaptation of the Marquis De Sade's "The 120 Days of Sodom", Paolo Pasolini's Salo is perhaps the most disturbing and disgusting film ever made.

It goes on to praise the moral issues and treatment of fascism, but quite frankly, I had difficulty seeing any redemptive value, and kept hoping that the credits were coming soon.

The film follows a group of teenage boys and girls abducted by Italian fascists during the Second Worl War.  They are taken to a mansion which is also a brothel and are subjected to all manner of indecencies by visiting fascist dignitaries.  Pasolini is a renowned Italian filmmaker, well known for his films of social and political comment.  His other movies are disturbing enough.  This one, though, reaches a depth of darkness that is hard to justify.
