Doctor Who: The Metebelis 2

From the first appearance of the original spud warrior in Norman England through to the "freakishly tall" Sontaran duo in Seville, Spain, Ben and David talk about Sontarans in classic Doctor Who. What make them good monsters for children? When do they work and when do they fall, ahem, short? All this in more in this week's episode. Opening music is from "The Invasion of Time" score by Dudley Simpson. Closing music is from "The Two Doctors" score by Peter Howell.
