Wow! You can't escape the fact that this movie pushes the limits of disturbing art! Many will call it sick. I suspect the point of this film is more about the depravity and dehumanization of fascism, political corruption, totalitarianism, and morality. I have not read the Marquis de Sade's work on which this film was based.
It isn't possible to "un-see" a film, so be prepared if you choose the experience. It was described to me as "horror" before I watched it, and I'm not sure it truly captures the film's genre. I can't think of a film genre that adequately describes it.
I will probably never watch it again or forget the images it seared on my brain. But I was challenged to think about various political and societal themes that are still very relevant today.
