Here’s to loving one of the least-hip shows on TV. To its earnest parenting, its destabilizing cast changes, its long seasons. Get excited for a cameo from Colin Powell, as himself! Marvel at the variety of accents being attempted! Can we interest you in some passionate descriptions of diplomacy and an occasional mention of Thomas Aquinas?

Buckle up, baby: It’s “Madam Secretary” time.

The CBS political procedural ended its six-season run Sunday, finishing off an abbreviated 10-episode season that found our heroine, Elizabeth McCord (Téa Leoni), fighting for her presidency. It was fine but often cheesy, even for a show that has a strong affinity for cheese in general.

Mostly this season struggled because there is nothing scrappy about being the president, and the show was always its most interesting when Elizabeth could justly play by her own rules. But there’s nothing to subvert as president; breaking with protocol is not admirable and is, in fact, often criminal.

And hey, the show was never called “Madam President.” (Or “Commander in Chief” — that was Geena Davis.) When it was at its best, though, “Madam Secretary” was a calm pleasure, a well-fitted dress shirt, thick stationery, shortbread cookies. Give us heated arguments in the Situation Room, but please, also give us Bebe Neuwirth, Patina Miller and Erich Bergen singing about international relations to the tune of “The Longest Time.”
