I didn't used to like modern art, but curiously enough I found that after listening to the music of modern composers for a few years, that I somehow suddenly understood modern art as well. I think unless one disagrees with some overt meaning or symbolism in the work, there is no reason to dislike any art. The whole purpose of art is to take us out of our comfort zones and force us to look at the world in a different light. Sadly, even many artists remain closed to unfamiliar forms.
