Watching things on DVD has an odd habit of hiding patterns in TV shows, as well as showing them. For all that watching classic Doctor Who exposes the runaround nature of some of the middle episodes in a serial, if you’re watching the show out of order, the links between serials go awry. Even if you decide to watch a programme like, say, George & Mildred completely in order, the fact that the show had a Christmas episode each year between 1977 and 1979 is easy to go unnoticed.
Let’s take some notice, shall we?
