> The Mona Lisa is a waste of canvas and oil - a hill I will die on

Seems like Mona Lisa elicits an emotional response in you as a viewer ;)

I get what you're saying though. I always "correct" people that claims some piece of music is "bad", there's no bad music, only music you don't like.

I think I read here on hackernews that the Mona Lisa doesn't look at all like it did when it was freshly made. If I look at the restored copy https://en.wikipedia.org/wiki/Mona_Lisa_(Prado)#, I at least find the silk very nice.

The Mona Lisa is a panel painting and doesn't use canvas.

I cynically believe that many people will force themselves into having an emotional response if the art piece matches with what they understand as having currency with the type of people they seek to emulate and the rarified scene they want to be a part of.
