Pollock is popular because of this exact thing. He "challenged" the idea of art as the Dada movement had done. You can absolutely hate it but like Warhol it made conversations and questions about process and astetics. By making a meme about it you have in fact thought about what art is and aesthetics you prefer. A Pollock painting made you do that.
People saying he do not select colors or use technique is just false. He would use a pulley system for large scale canvases and spread the colors quite purposefully. Remember this is the time of "happenings" like applying body paint and rolling on canvases, cutting up the canvas and applying newsprint, burning things, etc.
I don't even like Pollock but not to recognize him in museums within a moment of abstract expression would be a disservice. I've had plenty of students say. "I could paint that!". But there are two points they always misunderstand. 1. Pollock was an established painter who drastically changed styles. Many artists show that they can paint or draw in the traditional style but choose to push what is even art. Some people at this time said the "process" was art not the painting hanging in the museum. 2. Everyone who tries to replicate a Pollock typically just uses some random paints with some bushes and just sort of flings it around. If you actually look at a Pollock in person up close. Yes you can see unevenness is created from not having full control of the paint on the brush but thought seems to go into exactly where the paint will land so that you have even coverage or at angles with different brushes. They is motion in how the paint drips. I can say that many of them I've seen are very much not "random" as you would think it would be.
Again I don't care for the work as there are plenty of other abstract expressions to choose from like Hans Hofmann, Helen Frankenthaler who used Pollock as an influence.
