If the writing can bring invention to the thriller parts and smarts to the domestic parts, and invention, Hostages could have an indefinite hold on our imagination.
Sanders' husband (Tate Donovan) and teenaged kids are each shielding their own secrets, uncovered by Carlisle and his crew--and covered up by them as well. Unfortunately, they're fairly pedestrian.
The characters wander a spectrum from boring to irritating (guess which end the two teenage kids wind up on?), and the situation already feels unsustainable by the end of the first episode.
