Now in Colour! On this episode, the ESW crew reviews the first story arc of the Third Doctor, Jon Pertwee. Since The Doctor will be trapped on Earth for a while, we invited an author with a PhD to help analyze his predicament, David Layton (The Humanism of Doctor Who). Join the two Mikes and two Daves for an episode that can be summed up in one word. Just one word. Plastics.
