Speaking of dark, Laura Molzahn suggests you see the Same Planet Different World 15th-anniversary show, "Fifteen," which features Joanna Rosenthal's despairing It Is What It Is. Also good and dark are Theatre Seven's version of the Naomi Wallace play In the Heart of America and Redtwist's The Laramie Project: Ten Years Later. Keith Griffith recommends El Stories from the Waltzing Mechanics, and Kerry Reid likes what City Lit has done with one of her favorite Shirley Jackson stories, We Have Always Lived in the Castle.
Less enthusiastically received: Chicago Fusion's Las Hermanas Padilla, the Agency's Paradise Lost (not Milton's but Clifford Odets's), and Raven Theatre's staging of Arthur Miller's The Price. Zac Thompson protests that Sarah Gubbins's YA play about bullying, FML: How Carson McCullers Saved My Life, isn't dark enough
