It’s a minor theatrical annoyance, but one that does irk some critics: When your set displays a large wall clock, center stage, make sure it’s running. The wall clock in This Is Government, Nina Kissinger’s disappointing new comedy at 59E59, displays 4:55 in the 15-minute first scene and stays there, with the three denizens of Washington’s Cannon House Office Building moving the hands manually to tick off the subsequent scenes in a roughly seven-hour dramatic arc. It plays amateurishly, and so, unfortunately, does much of This Is Government.
