SEASON FINALE: This series, starring Sarah Jessica Parker and Thomas Haden Church as divorcing couple Frances and Robert, has picked up steam as it’s gone along, specifically in the mediation meetings featuring Frances and Robert and their respective attorneys. His is played by Dean Winters, who’s aggressive, sarcastic, and a bit slimy. Hers is played by Jeffrey DeMunn, who’s charming, confident, but mentally slipping. Their shared scenes, as when Frances explains the “tooth fairy sisters” she invented as stories for her children, have taken this show to unexpected, quirkily memorable places. And tonight, the story ends – but only for now.
