Would you attend a revival of a musical that sets The Sound of Music in Auschwitz? How about setting The King and I on the Bataan Death March? Mary Poppins on Mars, anyone? Broadway has lots of bad ideas. The current revival of Rodgers and Hammerstein’s Oklahoma!, the iconic American musical, is another. It’s not easy to turn an American classic about the joy of beautiful mornings and corn as high as an elephant’s eye in a land of open skies and endless promise into an attack on American gun culture, sexual politics, class discrimination, and a corrupt system of justice, but yippee-oh-ki-yay, director Daniel Fish’s revival—or, more accurately, his reinvention—has done just that.
