5. Feudal Japan: 1500- 1650
I admit that this would be very difficult to both cast and produce. But if handled correctly it could fit very well as an eccentric one-off like 'A Town Called Mercy' or 'The Crimson Horror.' What I have in mind is a Doctor Who tribute to the Jidaigeki genre and Akira Kurosawa's Samurai films. The villain/monster could be some dishonoured warrior who takes up residence in a fortress, and the Doctor has to work with the local Ninjas or Samurai to stop him. With such genre themes as honour, duty and purity of spirit, a day in the life of a Samurai could make for a decent Doctor Who epic.
