This framework and article don’t just apply to traditional painting art. This applies to any art: video games, movies, TV shows, books, even web design. Discussion of all of these things would be elevated if people can separate what is good and bad from their own preferences.

Edit: typo

It's really impossible to separate good and bad are from your own subjective opinion, as there is no true objective criteria that you can judge art by. There are criteria that can be chosen -- for example, how did the artist apply light to their painting -- but these criteria 1. depend on the specific kind of art (in the same vain, not all paintings utilize light in the same way or for the same purpose) and 2. are inherently subjective because they are being chosen by a subjective being.

The closest we can maybe come to being able to objectively judging art is as a collective/society saying that some art is good, and that the opinion holds true over time.

But that sentence isn't arguing for the notion of some "absolute good art". If I had to criticize it, it would be to say it doesn't go far enough by still accepting the concept of good vs bad art, whereas I think interesting discussions are multidimensional.

For example, why do you defend archeological architecture? Are the pyramids "good" because they are opulent? That sounds like a sensible stance at a glance, but then what of the Burj Khalifa?

Is Calvin and Hobbes not acclaimed? Is it not art? What of obscure manga about gender identity?

Why is Turning Red controversial? Who is it relatable to, and does that matter?

Suddenly equating one's opinion w/ "good vs bad" seems superficial. There's historical context, there's political commentary, and commentary on the commentary, and how that shapes the rest of the contemporary works.
