Was I alone in thinking of the Muppet Family Christmas while watching Doctor Who last night? There’s something about mixing the characters from more than one favourite television programme. It’s like a massive family get-together, of the fun kind.
Those Daleks make me think of cheese-graters with Christmas tree lights. Their leader – if that’s who he was – reminded me of Voldemort, which probably makes the good Doctor the Harry Potter of this adventure. And it’s always embarrassing when all your lady friends suddenly meet up together.
