While I don’t begrudge Big Finish creating their own little pocket of continuity within the Doctor Who universe, I still find it a bit frustrating when the script assumed you’ve listened to not only every release from one particular range, but also every release from the entire range of stories. Or that you’ve got an encyclopedic knowledge of that range of stories that you can easily call upon in order to understand the current story.
I’m doing well enough to keep my encyclopedia knowledge of televised stories up to date, much less that based on audio and literary adventures.
And so it is that I probably didn’t enjoy Destroy the Infinite as much as others who are more familiar with the range probably did. I came to find out from the extras on the disc that this story is a prequel to a previously released sixth Doctor story, Spaceport Fear. It seems that the alien race known as the Eminence made their first appearance there and that events in this story help set up that one. On the one hand, I’ll give Nicholas Briggs and Big Finish props for using the nature of time travel in a similar way to what the television series has tried to do. But on other hand, when I got to the end of this story, I was expecting it to be touched upon in the next several fourth Doctor stories and it never was.
It all led to my being more frustrated than entertained by this story — and curious to see out Spaceport Fear and see what happens there.
