The story is continuous, no slow build up, there is always something happening. Really enjoyed the music that was use throughout the entire episode, then here come the drums later was also use brilliantly. Was good to hear the Cloister Bell being used, a a trip down memory lane to the Doctor Who of old (might have been a good idea to explain it again for the younger viewers who never saw original classic Who but i suppose their plates were already full). Finally of course we have The Masters final words at the end of the episode, icing on the cake
