[T]he TV series now has a licence to contradict itself, and has already used it, big time. (In the original series, it just did that without having any such device. Three different versions of the destruction of Atlantis, two of them irreconcilable. Perhaps simple time travel, rather than a Time War, is all it takes to make history, canonicity and continuity meaningless.) That doesn’t mean we lose the lovely thought that Doctor Who is all one big story. It’s one big and very complex story, that rewrites and contradicts itself. That was always the case. Only now it does it with purpose, rather than by accident.
