#15 The Talons Of Weng-Chiang
Although Tom Baker’s Doctor in The Talons of Weng-Chiang is widely regarded as one of the best portrayals of the Time Lord, the story has aged poorly and is now largely unwatchable. The plotline was based on a crime has been committed in Victorian London, and the Doctor must solve it in true Sherlock Holmes fashion.
However, the episode is rife with offensive stereotypes about Chinese people and features white actors playing the Asian villains (in yellowface, of course). The story as a whole is extremely offensive to Chinese culture and has caused such a huge backlash that a warning is now shown before every showing.
