Doctor Who: Attack of the Graske
by Gareth Roberts; dir. Ashley Way (BBC Red Button, 2005)
A plush, interactive Christmas special aimed at young viewers. While David Tennant does his best to rise above the Choose Your Own Adventure format, the available choices are (severely) limited and the story, shorn of its gimmick, is an utterly banal non-starter.
Doctor Who: The Unicorn and the Wasp
by Gareth Roberts; dir. Graeme Harper (BBC, 2008)
Consciously overplayed comedy serving as a mid-season palate cleanser. David Tennant and Catherine Tate are obviously enjoying themselves. The story, while hokey, has enough of an idea to remain credible, poking gentle fun both at itself and at the murder mystery genre.
