Absolutely. And contrary to what some people like to think, their 5 year old children can not do what the Modern artists did. (And it appears that many people don't even know what "modern art" refers to.) Picasso is a common target, but what most people don't realize, is that he could draw and paint very realistically and in the "classic" style. His early works look nothing like his Cubist works.
I am actually very happy that we live in a time where artists are free to experiment with different ways of expression, instead of having to work under the approval of the "academy". I do find some work to be pretentious, and I don't "get" some more contemporary works, but I am very slow to dismiss something simply because of my failure to understand it. I really do try to discover more about the artist & their vision before I form a judgment about their work. As an artist myself, I wish more people were willing to do that.
I hope that my own position isn't seen as so simplistic as all that.
I would neither support "an academy of experts" nor the formation of hasty judgements.
I would attempt to say that Impressionism, for example, has some very complex works that took a good deal of skill to produce.
Nevertheless, I think they represent a degradation from the realism that came before, never mind medieval art. The chief degradation, to my mind, is philosophical, and a test which Impressionism (to take it as an example of a better modern art) demonstrates this in is its elimination of lines, which is really an elimination of definitions. Everything becomes pantheistically wedded to everything else, and like the very best lies, it is still recognizably close to truth. The fuzziness of the picture of the impression, which is already a replacement of truth with a subjective impression, reflects the fuzziness of modern thought, which increasingly fudges definitions and understandings.
So the result can still contain beauty, and perhaps even truth, though the truth becomes doubtful, which can make the impression itself a false one. Impressionism does not remove us so far from clarity as cubism and other, more degraded forms.
If I were to try to put it into one sentence, I would say that in general, modern art promotes subjectivism, the general denial of objective truth that we all ought to recognize. Truth and beauty are NOT merely subjective, and art that does not communicate truth or beauty is not art, and if it speaks in a private language known only to the artist, then the failure to understand is not in us, but in the thing that fails the test of art.
