Sunday TV: 'Madam Secretary,' 'Homeland'

Madam Secretary | CBS, Sunday, 8:30 ET/8 PT

Tea Leoni's Secretary of State has trouble on two fronts, as poorly guarded secrets are leaked — big ones in Pakistan, small ones in her own home. The solution to the big problem is the most complex the show has yet created, but the small problem at home has more of a ring of truth, perhaps because the parental byplay between Leoni and Tim Daly is one of the show's strongest early attributes.

Brooklyn Nine-Nine | Fox, Sunday, 8:30 ET/PT

What do you get when you put a guest who shouldn't be missed, Kyra Sedgwick, on a show that's fun to catch? An episode that shouldn't be missed, particularly since Sedgwick is playing Holt's (Andre Braugher) long-time nemesis. Sedgwick and Braugher trading jabs? I'm there.

Homeland | Showtime, Sunday, 9 ET/PT

This 2012 Emmy winner begins its attempt to persuade wavering viewers to return after last year's extremely disappointing run. The good news is there are some positive signs in Sunday's two-hour opener: It sets up an interesting new crisis that may re-establish Carrie as a competent agent rather than an increasingly unhinged mess, and offers a view of Pakistan and the CIA that is more nuanced than most. The cautionary note? The show got off to a decent start last season, too, and we know how that went.
