Ugly art, but perhaps a fine skating performance?

Gymnastics, figure skating, tap dancing, art, poetry. The list goes on. How can such performances be properly judged? Olympic judges would often significantly disagree on the quality of a routine (such as Nastia Liukin’s uneven bars tie). I usually just go by the aesthetics of the performance. If it seems fluid and artistically sound, then it is good. Plus, judges know when do deduct for technical flaws. But one question still remains: what makes good art? The use of color, line, texture and subject matter are a start. I just don’t know where it goes from there. I often look at something and think it is sound, but realize that the authorities [critics] have different feelings. I could write a poem about a personified vegetable and think it’s the greatest thing in the world. Too bad the beauty is in the eye of the beholder.

Undeniably good: Albrecht Durer's "The Four Horsemen of the Apocalypse"
