Weekend TV: 'Missing,' 'Madam Secretary,' 'Once'

The Missing
Starz, Saturday, 9 ET/PT

This international import stars James Nesbitt as a father haunted by the disappearance of his five-year-old son. The eight-episode drama traces his hunt for his child, and the effect the search has on his relationship with his wife (Frances O'Connor).

Madam Secretary
CBS, Sunday, 8 ET/PT

Broadway great Brian Stokes Mitchell stars as the late Vincent Marsh, as one of the season's more improbable hits doubles down on its continuing story of the mysterious death of the secretary of state. So much of Secretary doesn't — or at least shouldn't —work, starting with this conspiracy and moving on to Henry's secret spy mission and the show's desperate attempt to make a couple out of the chemistry-free Matt and Daisy. (No one is ever going to call them "Maisy," CBS. Just – stop.) And yet it remains one of the new season's more dependably entertaining hours, thanks in large part to very appealing performances by Tea Leoni and Tim Daly, who make their characters and their relationship feel credible, even when common sense tells us they're not.

Once Upon a Time
ABC, Sunday, 8 ET/PT

Here's good news for fans of this Disney-fueled fantasy: It's expanding to two hours this week. The double-length outing is built around the Snow Queen (Lost's Elizabeth Mitchell), who's up to no good in the show's version of Frozen.
