There’s no getting away from it. It’s not just that the Denver Center has the resources to ensure a certain level of consistency; it’s that the company also has the integrity to put on a solid roster of plays, including those of Shakespeare, Pinter and such modern wonder boys as Martin McDonagh while remaining willing to take necessary risks — original scripts, for example, and a highly successful production of Thornton Wilder’s puzzling and intriguing allegory, The Skin of Our Teeth.
