No, not the Gerry Anderson 1990s cops-in-space series, though I’ve been asked to do that one next by readers who like making me watch bad television so they don’t have to, so I’ll be starting it in October, after a couple of palate-cleanser articles. You were warned.
Meanwhile, on The Starlost, Garth decides to split with the hero trio (now back in their cotton shirts) for no sensible reason (he says they’ve been wandering the Ark for months and achieved nothing, which is fair, but how the whole “we’re all gonna die if we don’t move the Ark” thing will be furthered by him going solo is unclear), and takes a left turn into a whole different subgenre.
Suddenly we not only find that the Ark has some kind of police force (who have apparently been keeping tabs on the trio but doing nothing about it), but that there’s a whole interplanetary federation of humans who are engaging in interplanetary political shenanigans, cold-war espionage, and so on, which this police force are involved with. Meanwhile, Devon and Rachel literally spend the episode in a stalled elevator.
All the usual The Starlost problems are there, too; weirdly flat acting, characters whose motivations and personalities change from minute to minute (first the police chief is begging Garth to join the force, then he’s accusing him of inviegling his way into the force to spy on it), bizarre inconsistencies in how the Ark works and how much danger it’s in (Garth keeps on about how he thinks he can build a life here with the police force, while the rest of us say “until you meet your firey doom, that is”), and velour jumpsuits that must make going to the bathroom a challenge.
And the whole series ends with a sort of a whimper. Devon and Rachel trudge off on their seemingly futile quest, and it’s ambivalent whether or not Garth will rejoin them or stay with the police, suggesting that someone was making a desperate bid to keep the series going by changing the format completely, making it a series about space cops in an interplanetary federation and sidelining the quest story.

But then again the series forgot its USP a while back, turning from a story in which the hero trio visit biospheres with different cultures and different problems into a formula where the hero trio wander into a workplace led by an older man with a female sidekick, get into trouble, and wander out again. At this point it was probably unsaveable, so ending it there is probably merciful, for the characters as much as the audience.
