To see or not to see: Was review of musicals fair?

Sun Times: "The facts regarding my review of Stages 2006, the festival of new musicals produced earlier this month at Theatre Building Chicago, are clear and simple and of crucial importance. And had these essential facts been investigated by the powers that be at the Dramatists Guild of America, and all those distinguished members of the Guild who so blindly and unthinkingly engaged in a letter-writing campaign based on a total lack of honest information, the attack launched against my ethics might well have been reconsidered."
