DVD: Doctor Who Christmas Special: The Doctor, the Widow and the Wardrobe (PG)

The best Doctor Who Christmas Special for some years is set during the Second World War where Claire Skinner's plucky Madge Arwell has just learnt their her bomber-pilot husband (Alexander Armstrong) has perished in his plane.

Cue the arrival of the Doctor (Matt Smith) to put things right. The Time Lord whisks Madge's two children off to a snowy wonderland, which, of course, is about to be attacked (by acid rain). The eco-message is a bit laboured, but the central tragedy that powers this scatty episode is a poignant one.
