The Sensorites!
Companions: Susan Foreman, Ian Chesterton, Barbara Wright
Doctor: 1 (William Hartnell)
Okay, so there are the Sensorites and they are keeping this human crew from leaving and when the Doctor and co. arrive they are also kept from leaving. There is a big hullabaloo and misunderstandings and Susan is all telepathic or something. The Sensorites don’t really want people around any more because they fucked up so much shit. Basically humans are giant buttholes in this episode. Eventually everyone is allowed to leave, even the crazy-ass humans. I mostly remember this episode as: the one where Susan screams about her damn headache/too many Sensorites in her brain. Someone out there probably likes this episode, but it sure isn’t me.
