I remember how at the university I stood in a queue and talked with my girlfriend about the "The Human Centipede," the guys at the back heard our conversation and looked at us like real psychos who are interested in such trash))
I watched all the movies from your list. Many of them win not with an idea, but with vile frames that are remembered and averted for a long time. For me, the worst of the proposed films is the “A Serbian film”.
