Another one of those very creepy episodes, on par with ‘Listen’, earlier in the series. Once again, some fine acting from all concerned, with the twist that Clara and The Doctor swapped roles. But was it any good? Well, I enjoyed it, although I suspect that the internet will probably be buzzing more about the last few seconds, than the episode as a whole!
!I won’t spoil it here, but suffice to say, the much under-played story-arc is starting to reveal itself!
