I read a discussion a while back where a few people trashed everyone who's a fan of Salo and it got me thinking.
This is because these people don't understand how art can function. It's one of the great fallacies that comes with thinking that movies are primarily made for 'entertainment purposes'. And why thinking of film through this specific lens narrows its value where people start to think watching something like Salo is about those in the audience being 'entertained' by the atrocities being committed on the characters.
Obviously film CAN entertain. But the over arching point of film needs to be defined much more broadly as something that is used to make us look at life and beauty and feelings and thoughts from different vantage points, and come away with a greater understanding what it is to be alive. To be an individual. To be a member of a community. To be a patriot. To be a revolutionary. To be a romantic or a nihilist. Film grants us passports to different ways of looking at the world, and a film like Salo (in short) allows us to contemplate the way in which authoritarianism manifests in society. How it warps those in power and how it affects those beneath such thumbs as these. It explores the relationship between these two groups in a way which is deliberately discomforting. And we don't watch it to be entertained. The better word, is we watch it to be engaged. And to hope to understand.
When people only comprehend art as something to passively accept while they watch, and to only reinforce previously held beliefs as they pass the time, and to never challenge establish norms or morals or political stances, then that's how we get these dullards out there who can only look at the violence of Salo and shake their head and wonder what's so fun about shit-eating.
It's just a bad bad bad bad bad opinion to judge anyone's personality on their taste in film, without there first being a discussion of what they think films can do. And what they are getting from it. Admittedly, a lot of people are still not going to grasp this, even after a good long talking to. But you can't save everyone from their paralyzingly awful opinions.
