If Peter Capaldi (or at least his eyebrows) doesn’t receive a BAFTA for his portrayal as the Doctor this series, it will be nothing short of a crime against the arts. There are very few actors capable of carrying over 50 minutes of television almost single-handedly and making it something worth watching over and over again.
Before I go any further, a warning: this review contains spoilers! Big, fat, juicy spoilers that will most likely ruin your enjoyment of another otherwise incredible episode if you have not yet watched it. I have left this review enough that most people will have seen Heaven Sent, but if you still haven’t and if you do not want to know what happens, please do not read on. There are also minor mentions of the public revelations – and personal theorising – about next week’s tantalising finale. If you have been avoiding those, too, please do not read on. You have been warned!
