A really cool episode of Doctor Who is the Talons of Weng-Chiang, where the good doctor and his lady Leela come to 19th century Victorian London, and there's a big plot involving a 51st century Chinese "Lord" who's trying to get a device together so that he won't die off (he already wears a chintzy black mask). It is, par for the course of a Doctor Who mystery, a bit more convoluted than maybe necessary, but that's part of the fun in figuring out what will happen next. There's a lot of servant-and-master stuff between "Chinese" magician (in quotes as it's really a white guy in make-up, probably a savage joke at old stereotypes) played by Christopher Benjamin, and some solid, very 'British' dialog between some supporting characters, and a little guy in a mask (played, I think, by the amazing Deep Roy) and a giant, Rodan-esquire rat! Overall the episode might be a little sluggish in parts, but for the most part it's as close to a classic as fans can hope for. Especially with Tom Baker at the helm, who makes the doctor a bad-ass sort of in the tradition of a Jack Sparrow character (almost without trying, and by luck, he gets his way against those against him), and is of course very funny beneath the seriousness of the story. And, by the way, there's magic! And some cool twists like someone you didn't expect in that box stuffed with swords!
