Even if you buy that argument, your tolerance for its expression may be greater than mine. I don’t feel improved, enlightened or even chastened by a furious man repeatedly cracking a bullwhip in my direction. Nor was I amused by the dragooning of theatergoers brought onstage to witness atrocities or, at another point, to be turned, without warning, into slaves at an auction. The close-ups of their faces, as they crumple or freeze in the act of realization, are devastating, and not just for those undersold at $1. The devastation is of course the point. Everything “Dark Noon” chooses to explore figuratively was once quite literal to its victims. That there were millions of those victims lends moral importance to the endeavor — all the more reason it must be done well. But the play’s format seems to have gotten away from its values, creating a disturbing symbolic alliance between the storytellers and the perpetrators. It is no longer a representation of cruelty; it is cruel.
