Tonight’s broadcast line-up is nothing but reruns. The week between Christmas and New Year’s is essentially a television dead zone, with even many cable networks opting to run repeats. That can be frustrating for those of us who love TV. I am marathoning this entire season of Dexter, which I DVRd but never got around to watching. I am looking forward to New Year’s Day when NBC will air a new episode of Parenthood. How are you surviving?
