Me, neither. Nor Klee, nor Jackson Pollack, nor any of that other stuff they rave about. What a scam. Just no one has shown up and said the emperor is naked (far too much money tied up in that, now.
My view is that 20th century painters realized that they were unable to match or exceed the work of the greats of old. So, they came up with new, weird techniques to fool the masses. They got the art critics in on the scam to try to trick the public into believing they were seeing great things instead of blobs or screwball shapes on canvas.
I remember watching some doc. on tv about modern painters, and they showed some of the work of Mark Rothko. One of his paintings was three different colors painted in curved lines on canvas. That was it.....just three different colors. It really looked like something a kindergartner could fingerpaint. The critics raved about it. And you're right about Pollack. His work is total crap.
I think Tom Wolfe wrote about the feeling of being duped by the modern art world in "The Painted Word."
