One of the most underrated sitcoms in television history, "Petticoat Junction" is a fine example of character-driven comedy. Though it is overshadowed by the other rural comedies, "Andy Griffith," "The Beverly Hillbillies," and "Green Acres," "Petticoat Junction" had a warmth that continued throughout its 7 year run. The episodes before Bea Benaderet's untimely death are perhaps the best, but "Petticoat Junction" remains one of television's undiscovered gems.
