According to Moore’s model of Ideaspace, this fiction may be complicated enough to act like a living thing. Note that this is not to say that Doctor Who is a living thing, for that would sound crazy. It is to say that it behaves as if it were a living thing, which is a much more reasonable observation. Of course, if you then go on to try and define the difference between something that is living and something that behaves like it is living, you will be a brave soul indeed.
