SEASON PREMIERE: Like so many miniseries-style series popping up these days, The Missing presents a new story, with a largely new cast of characters, each season. For this new season of this imported British drama, David Morrissey, not too long ago seen as the governor on The Walking Dead, joins the cast as the father of a missing girl, who has been gone for more than a decade, but may have suddenly resurfaced. And if you like tonight’s premiere, you can keep going, instantly. While Starz the TV network will continue to unveil episodes weekly in this Sunday time slot, visitors to the Starz website can watch the entire Season 2 immediately.
