There are lots of famous artists whose work I honestly cannot appreciate and don't particularly like or care for. I don't think that's bad or wrong. It's a matter of personal tastes, and we're all entitled to our likes and dislikes.
It also has to do with how we learn and how we've been taught. Some teachers insist on teaching WHAT we're supposed to like; I refer to them as educational despots that believe we should "like" what they were drummed into liking, mostly because it's "traditional" thought... forgetting that innovators were despised by traditionalists that were mostly failed artists that became "critics," who stalled and crippled advancement and new styles... much like what the great Impressionists encountered and endured throughout history. These "educators" forget and ignore that we can and usually do make up our own minds on what we like or don't like as a matter of personal tastes.
People stand in art museums and stare at paintings... many don't know or understand what they're seeing but they go through the motions and rituals of the "learned" to give an appearance of being "sophisticated," and some can repeat by rote what they were taught or they've read... just to fit in with the so-called sophisticates and supposed intelligentsia.
My favorite story about art is one I read in the NY Daily News about a museum curator droning on and on about a particular modern art work by a famous painter to a class of middle school children. He was yapping about the "power" of his strokes, his use of colors to denote how this and that represented this and that... There was silence throughout the huge room as museum visitors listened when suddenly a child finally said, "Mister, that painting is upside down..." Naturally, the curator scoffed at the child but the child insisted, "It's upside down... that's not how it looks in my art book." A few days later, the painting was discovered to have been mounted upside down for many YEARS. So much for that curator's schpiel, eh?
