This episode: we pay the Cat Tax, somehow this serial is only four episodes and not six, the podcast hosts can NOT stop talking about The Mutants, a twitter poll enrages Rosie beyond reason, and we have a sprawling debate about the conflict between NuWho and its eternal desire to reinvent the UNIT fam. As ever, do encourage other people to listen to our fun little show, and get in touch with us @PolarityPod on Twitter or at polaritypod.tumblr.com.
