Ugly? wish you'd elaborate a little.
I get sucked into ballet despite my better judgement. Although I generally feel it's a weird and distasteful aesthetic, it's seductive, like planned communities, Shaker villages, Playboy bunnies. I suppose I think dance is more temporal than other arts, doesn't keep well.
Modern ugly? Kind of a big sweep, there. Well. Compared to polka, or Appalachian clogging, or urban breakdancing, or the fox trot, or the mashed potato, sure, but still. Gee.
