“My goal is to write plays with exciting stories, smart characters and sharp dialogue. The reviewers report that my plays are full of philosophical ideas. So be it. I’m tired of plays about dysfunctional families and jumbled identities. For me, ideas are more exciting.” So goes the program bio of Douglas Lackey, author of Hans Litten: The Jew Who Cross-Examined Hitler, a new historical drama at Theater Row. And he’s true to his words, or at least two of them: “philosophical ideas” dominate, sometimes at the expense of character development, tension, and atmosphere. What’s onstage isn’t uninvolving or unmoving, but one is very aware of what’s missing.
