“Is the government of the United States evil?” That’s the search query that sends one computer nerd into a Kafkaesque approximation of Guantanamo in the dark, dark comedy Don’t Be Evil. (Yes, it’s funny, and yes, the title alludes to Google’s official motto.) Buried in paperwork, two agents (Allison Crews and Andrew Iacovelli) vacillate between exhausted and bumbling as they violently interrogate a web developer (Dillon Medina) whose new search engine is a little too thoughtful for its own good. Burbage Theatre Company’s well-acted production is minimal, which seems fitting since the play is set entirely in a series of identical-looking interrogation cells. Jim Sullivan pops up halfway through as a Dennis Hopper-style executioner.
