To his credit Mark Gatiss does manage to swiftly build a sense of a complicated, multi-layered society and its a shame we are not allowed to know more of it. The conceit that India and Japan have merged after a cataclysmic disaster is an interesting one as are the polytheist undertones. Combine that with a culture of drones and workaholics and youve created a fabulous framework to set a story in. I want to go down to that moon and wander around in that environment as I have a feeling its more interesting than whats happening on the space station. Peter Capaldi skips up to the edge of pretension as he grimly recites lines of Shakespeare and the breaking of the fourth wall becomes tedious. Still he continues to exude an aura of otherness that is a joy to watch as he flits about trying to figure out what is going on. He takes charge effortlessly and keeps the story from getting too bogged down in its myriad of details. While the other characters fall flat Capaldis Doctor is lovingly written and never drops the ball. He is the strength of the episode.
