Shame is an overwhelming emotion. When it mixes with religion, it becomes an explosive force. Two plays this week go right ahead and light the fuse: Hesperia and Disgrace. In the former, a porn star joins an evangelical community, hoping to regain her innocence. In the latter, a corporate lawyer tries to run as far away from his Muslim upbringing as he can. Reader critic Zac Thompson recommends Hesperia, saying that playwright Randall Colburn paints his characters as, well, real characters, rather than chick tract stereotypes.
