It begins with a funeral. It ends with a funeral. In between are jarring gun shots, explosions, fire, war, revolution, murder, suicide, blood, death—and everywhere passion, passion for a loved one, passion for a cause, passion for a home. The story of Doctor Zhivago, adapted from the movie based on the novel by Boris Pasternak, is huge, sweeping in scope. Even with a few lovely musical moments and some fine performances, this is a heavy, heavy evening in the theater.
