Glad you are big enough to take my jab at your pic ( you are one of the last people I would want hunting me down...)

Maybe part of the reason most people don't appreciate some art is it takes work.
Getting to know a piece of art takes as much effort as getting to know a person, which in essence a work of art is.
The more you judge it by your prejudices or by what you already expect to find, the less you will learn and understand.

Also, a knowledge of the artists lifetime of work (if they are in the past) helps, but again that takes effort.
Pollock didn't just start with his action painting, it is a story developed over time and the beauty is in how it all came together in that period/style. Then it all fell apart for him.
The overwhelming majority of "artists" are never are able to get past that agonizing first phase of breaking through the wall of what is known and has been done before and the ridicule of those who don't have time or patience to try and understand the heroic (that is the apt word) efforts it takes to keep at it (through poverty and physical suffering for many) and make something coherent out of it.
If they do make it through, that is where the masterpieces lie. The ones that have a calm understanding and clarity; like "One", or "Lavender Mist" or Autumn Rhythm" ( though it is fair to call the rougher evidences of the period of struggle masterpieces, like "She Wolf" and "The Troubled Queen").
Then they are faced the the other wall of the hurricane - leaving behind what they now understand and going deeper in to the unknown psyche.
Very very few get through that one. Most get comfortable in a style and remain comfortably (Monet), or maybe uncomfortably (Manet) frozen there , selling their work and eating the not undeserved praise.
The very Greatest - Cezanne, Picasso, Rembrandt, Michelangelo, Shakespeare,
Beethoven, Newton, to name a few...just keep diving deeper and deeper and bringing back to us previously unimaginable things..

IMHO
