A London family flees the bombing of World War II and comes to a country estate, where two children and their mother discover a doorway to another world… but what lies on the other side is definitely not Narnia. Instead, it's a wintry forest planet on the brink of destruction, and only the infinitely clever time-and-space-traveling alien being known as the Doctor (Matt Smith) can figure out how to save it.The Doctor, the Widow and the Wardrobedoesn't have the complex story of the lastDoctor WhoChristmas special,A Christmas Carol, and the Doctor coming into a family's life and making it better veers perilously close toTouched by an Angelterritory--but what makes up for it is the rich creepiness of the snowbound forest and the eerie creatures who live there. As with any Steven Moffat script, the dialogue is smart and sprightly. And Matt Smith, with his deep-set eyes, gangly body, and effervescent fusion of whimsy and intelligence, continues to develop a multilayered incarnation of the Doctor that's as compelling as any that's gone before. Extras include a very peculiar look back atDoctor Who's sixth season, in which an odd mix of artists and celebrities (including alternative comedians like Reggie Watts and Eugene Mirman, Amanda Palmer of the Dresden Dolls, magazine editors, podcast hosts, and random actresses) enthuse about their favorite aspects of the show.--Bret Fetzer
