Has art jumped the shark after WWI?

[abaris]

It comes down to how well does the final product demonstrate the understanding of the medium that the artist had.

The more fudamental view would be, how well did the artist manage to reach an audience. In short, I don't give critics much credit. Sometimes their judgment is in accordance with mine, but sometimes it isn't. Which only proves that art is a totally subjective experience. It speaks to you or it doesn't.

But that doesn't mean I'm unable to appreciate things I personally dislike. For example, Arnold Schoenberg doesn't reach me, but I appreciate that he introduced something entirely new to music.
