Quote:Doctor Who has no canon
Congratulations! You've successfully bought into another Nu-Who showrunners' myth.
EVERY ongoing series - whether tv show, film, books or whatever - has a canon. A history.
The Big Finish audio dramas gave an ending to the time war that was later flatly contradicted by what we saw on screen. In the comic strips the Hartnell Doctor has two pre-teen grandchildren, John and Gillian. The comics prior to 2005 also have a completely different 9th Doctor, based on Nicholas Briggs. The film Doctor was an earth scientist who created a space/time machine, and had two granddaughters.
None of the above is ever referenced in the tv show. Why?
Because none of it it canon.
The tv show has it's own unique history, separate from the other media, each of which have their own unique bodies of work.
To be fair, while there is a canon, it doesn't mean there is just one canon. You can make the argument that there are three different continuities: the original series, the TV movie, and the current series. For each continuity, everything that happened before is canon, but that doesn't have to mean that everything that happened after is canon. If you're a fan of the original show but hate the current series, that's fine. The new series shouldn't ruin how you feel about the old series because you can ignore the new series. The creators of the current series can also pick and choose what from the original series is canon. There's no rule that says they have to accept it all. If I recall, the current show was a few years in before the previous eight Doctors officially became canon on that show.
