Ok, by no means the greatest, but certainly a very credible story for the 4th Doctor, and with some very interesting dimensions to the story. There seems to be elements relating to tax, i.e. a corridor called P45 and the guards being the internal retinue, but also a lot of suggestions that the story was also about the BBC at the time and the bureaucratic nature of the organisation.
Whichever it is, or even if it is both I don’t mind really. It was a good story with some interesting ideas and of course a performance from Blake’s 7’s own Michael Keating which pre-dates his role as Vila.
I enjoyed it anyway.
