Last of the Time Lords. Break-taking, magnificent. A huge story, that sidelines everyone and places Martha Jones front and center. And what a fantastic Companion she is! Performance-wise: Freema Agyeman and John Simm are a joy to watch, she’s the heart of the story and he’s giving a performance so big, it’s pretty much fills the universe. Remarkable achievement, this episode. As, indeed, is Doctor Who itself. 10/10
