In the collection of disturbing films, you will find many genres, all of which tell genuinely powerful messages. However, there are those movies that are just plain evil and have little to no artistic value and exist solely to make you want to vomit. The exception would be Pier Paolo Passolini's Salo, The 120 Days of Sodom, which exists as an artistic and cinematic treasure by the late Passolini, yet this film is still universally vilified as the most disturbing and utterly vile film ever made.
