In Aardman's latest animation, a graphically accomplished but otherwise rather commonplace 3D seasonal offering, three generations of the Christmas family start arguing about their business (reindeer-drawn sleighs v spaceships) after a present for a little girl in Cornwall is discovered undelivered in the firm's new hi-tech north pole HQ. The accident-prone grandson Arthur comes up trumps after a series of wrong turns. An odd Anglo-American collaboration that will bring a little brief happiness to undemanding children.
