I don't like to start reviews with questions, but New Ground Theatre's current production of Lobby Hero raises some interesting ones. (1) Is a hero someone who, when faced with a moral dilemma, reveals deep dark secrets that will get a friend in big trouble? 2) Does sliding indifferently through life without ever changing viewpoints, challenging ideas, or standing up for personal rights gain someone hero status? The answer to both, obviously, is no. A hero is defined by my dictionary as "a man of great courage, nobility, etc. or one admired for his exploits." So what was playwright Kenneth Lonergan thinking when he used a lazy, noncommittal lobby security guard as a protagonist of his play Lobby Hero?
