I know I've been talking about Doctor Who a lot lately, but it was that good. The fiftieth anniversary special was amazing! Rather than taking the view that an anniversary special just means showing pictures of all the Doctors in some kind of dramatic exciting fight that doesn't make any sense if you think about it for half a second, they did that bit in just one throwaway scene near the end and spent most of the 75-minute episode doing genuinely clever things with the concept of time travel - something that the 21st-century series generally hasn't done at all well so far. This story, though, was intricate in its construction, with lots of little moments that get a big thumbs-up from me, and the three Doctors and Clara were wonderfully characterised!
I'm happy now. Just keep making Doctor Who, please!
