Some say that Doctor Who is only as good as its guest stars. If that were true, then “The Snowmen” is golden — a perfect segue from Amy and Rory’s sudden exit to the fun mystery of the Impossible Girl.
Not only does it have fantastic guests, its setting is chillingly gothic. The wintry atmosphere of Victorian London not only perfectly communicates the Doctor’s depression at losing Amy and Rory, it also provides a great environment for a genuinely scary Christmas special, perhaps the first in the show’s history.
