The first sitcom to be built on some of the tenets of modern feminism (and not in a jocular way), One Day At A Time was quietly groundbreaking in its day, depicting life for a newly divorced mother (Bonnie Franklin) and her two daughters (Mackenzie Phillips, Valerie Bertinelli). Co-created by actress Whitney Blake (Hazel), who knew something about divorce and single motherhood, the series' mere existence was testimony to how network programming standards had changed in the previous five years -- before that, a comedy about a divorced mother would have been unthinkable on CBS. This Sony two-disc set contains the 15 episodes from the series' first season. They've been well-preserved, at least in the main body of each show -- it's disconcerting to see how badly faded the opening credits' film image looks, but the shows themselves look alright in clean full-screen (1.33-to-1) transfers. The opening menus are easy to use and maneuver around, and each episode has been given a paltry four chapters. Unlike some other Sony television DVD releases, there don't seem to be any gaps in the content of the shows that are here, and there have been no alterations of the music. There are no special features.
