The eight-part drama that begins Thursday stars Maggie Gyllenhaal as a British baroness with an Israeli passport. She's a fearless actor in a show full of kidnappings, seductions and betrayals.

This week, two new TV series begin in the threats-from-nowhere genre: Extant on CBS and The Strain on FX. The better of the two, The Strain, about a disease outbreak, is effectively creepy.

The late-night talk show, imported by BBC America, has been around for years. TV critic David Bianculli says it's never been better — it's like eavesdropping on an all-star cocktail party.
