When the lights – and all computers, telephones, car engines, and batteries – go off permanently and seemingly forever during the pilot of “Revolution,” the audience is left in the dark for only one or two minutes. Then, 15 years later, sunlight shines on a rural village, its good guy leader is killed by one of the militias that roam a dystopian America, and a fascinating idea becomes trapped in a mixture of stereotyped characters and stereotyped plot. The pretty teenage children of the dead man –the girl Charlie (Tracy Spiridakos) and the boy Danny (Graham Rogers) – come from central casting.
