Eclecticism has always been essential to Mr. Guare's writing, which at its best juggles mismatched elements of culture, high and low, with daring and dizzying skill. This is the man who memorably combined tabloid prurience (and famous-name dropping) with classic poetic lyricism... But here, in his first new play on Broadway in 18 years, he seems less to be juggling than tossing bright balls of allusion and information onto the stage and praying that they'll land in a coherent pattern.
