As per their normal routine, Petter Mårtensson and Breki Tomasson return to the land of Doctor Who and watch another serial. This time around, it's The Hand of Fear, an episode about an entirely 'armless hand that still manages to cause all sort of trouble - until it stops. And then starts again.
It's all a bit confusing, really.
