Doctor Who has been delivering sci-fi adventures for over 60 years now, but just because it has a long history doesn’t mean it’s always been watchable. In fact, a number of episodes are quite literally unwatchable — 97 episodes from the show’s first six years are now considered lost, victims of the BBC’s protocol of taping over existing programs.
But even within the surviving episodes, Doctor Who didn’t look like the snappy episodic show we see today. For much of its run, Doctor Who’s stories were structured as serials, a single adventure told over multiple episodes. It made for more deliberate pacing, but it also means it’s harder to catch up on the archive. But now, one of the most important serials in all of Doctor Who is getting a new look, perfect to reintroduce modern-day fans to Doctor Who’s strange past.
