2007's Doctor Who Christmas Special made for hugely enjoyable entertainment with its lively, and typically endearing, blend of melodrama and 1970's disaster movie. David Tennant, as ever, throws all his nervous energy onto the screen ably supported by a fine cast. Clive Swift plays a winning and joyful Mr Copper; Kylie, of course, is Astrid Peth the little waitress with the big dreams and Russell Tovey is the indefatigable midshipman who somehow stays the course. But I'm telling you the plot! Two thumbs up. Watch and enjoy with all the family.
