This is a post-UK broadcast review of Doctor Who: The Pilot. River Song always warned the Doctor against spoilers, so be sure to watch the episode first. Episodes of Doctor Who air on Saturdays at 7:20pm UK time on BBC One, and 9pm EDT on BBC America.

This is not a Dalek episode. It’s a “bigger on the inside” episode. But it also adopts an obvious lesbian psycho trope—which is a pity: outgoing showrunner Steven Moffat makes the Doctor’s new companion gay and her first encounter with a monster happens to be an unhinged, shape shifting stalker who repeats everything Bill Potts says while dripping water onto the floor. Poor house guest, certainly. And probably not someone you would want to bring home to your family.
