@CriticalCupcake Anniversary specials can be hit or miss, and this one was mostly hit. The villain was suitably nasty (we were waiting for the reveal and it was not disappointing), the threat of destruction comically ridiculous, the gobbledegook predictably nonsensical, but it was all fun and totally of a piece with where RTD left things over a decade ago.
I don’t think it can be understated how vital the positive trans representation in the episode is, given the state of bigotry in the UK. The fact that all of the usual suspects started churning their bile is evidence enough the show got it right, albeit clumsily.
