From der Wiki:

Saying you can paint a picture like this means nothing. Any competent artist can. Newman did it first. It didn’t spark a trend of rectangles with zips. It made a distinct, unique statement. Find something original to say and then you have the creds to argue against the authorities. “I don’t like it” repeated ad nauseum isn’t a valid argument against the hundreds-to-thousands of people who’ve studied it and found it’s important. At the very best, it’s mere solipsism.
