This is the third episode of this new NBC series, which continues to entangle the three suburban buddies – played by Christina Hendricks (Mad Men, Another Period), Mae Whitman (pictured, from Parenthood) and Retta (Parks and Recreation) – as unwilling agents of a fierce local mobster. In tonight’s installment, “Borderline,” he sends them on a mission to cross the border into Canada and bring back a mysterious package. Making them reluctant agents of a powerful blackmailer is no different, really, than the relationship Robert Wagner’s cat burglar had with his government “handler” in the 1960s classic series It Takes a Thief – but this show, so far, is one-third It Takes a Thief, one-third Charlie’s Angels, and one-third Desperate Housewives. But even with these three elements, and very likable female stars, Good Girls has yet to live up to its title, and gel into something Good.
