Robert Gottlieb looks back at a season of dance that didn’t add up to much. “Large talent, of course, can’t be legislated into existence, and it’s not the fault of the Rhodens and O’Days and Kudelkas and Greenbergs that they don’t have it. But let’s not be deceived by the culture’s machinery of publicity and self-promotion or by our ardent longing for the real thing. That we have so few first-rate choreographers today is a sad fact; better to accept it than to lie to ourselves.”
