A nurse from London is abducted by robots because an ex-boyfriend once bought her a novelty star certificate, and the planet that grew up around that star has spent years worshipping a woman who has no idea it exists. That’s a genuinely good hook, and “The Robot Revolution” does surprisingly little with it. Varada Sethu arrives as Belinda Chandra and is immediately the best thing in the episode. The episode itself is a muddle.
After a Christmas special and a full series, this is the third attempt at a proper opener in this era, and it repeats the same habit. It throws a lot of ideas at the screen, resolves them at speed and hopes the charm carries. It mostly doesn’t. The last two minutes set up a better series than the forty-eight before them suggest, which is at least something.
Belinda is a strong addition
Sethu plays Belinda as a working nurse with no patience for any of this, and the difference from Ruby is immediate and deliberate. Ruby wanted to travel, but Belinda wants to go home, says so repeatedly, and treats the Doctor as an obstacle for most of the runtime. The scene where she tells him flatly that she isn’t his companion and has a shift to get back to is funnier and sharper than anything in the previous series opener. We meet her at work first, tired and competent and mid-shift, before anything science fictional happens. That small choice pays off, because every complaint she makes about wanting to go home has a real place to go back to.
The backstory is nasty in a useful way, too. The star certificate was bought by a controlling ex, so the entire planet’s worship of her is founded on a man’s gesture of ownership. Sethu plays Belinda’s discomfort at being worshipped as a direct extension of her discomfort at having been possessed. That’s a story about how casually things get assigned to women, and about being made into a symbol you never agreed to be. All of that is present in the setup, and almost none of it is present in the episode, which is far more interested in getting to the robot siege.
The plot never settles
The trouble is everything around her. There’s a robot uprising, a human resistance, a planet named Missbelindachandra, a tyrannical AI Generator, a twist about the ex-boyfriend and a time-travel fix, all inside fifty minutes. The AI Generator turns out to be Alan, the ex, fused with the machine, and the episode wants that to land as both a personal horror and a satire about artificial intelligence without building either properly. A man who wanted to own one woman ends up owning a world and still defines it entirely by her, which is a proper idea with a proper shape. The episode has about four minutes for it, plays it as a shouty confrontation, and blows him up.
The satire is the weaker half. There’s a gesture at AI as something that consumes people’s work and identity, which is a rich subject, and the episode raises it and immediately moves on to a corridor. The Sound of Drums handled a contemporary target far better, because the satire about a media-built politician was the plot instead of a coat of paint on it. Here the theme is a costume the villain happens to be wearing. The whole hour rushes past its own best material, and this is where it shows most.
The robots deserved better
There’s a decent design idea in the robots. They’re bulky, industrial, slightly agricultural machines instead of sleek killers, and the sound work on them is good, all hydraulic wheeze and metal complaint. They look like things built for a purpose by people who couldn’t afford anything better, which fits a colony world. There’s one properly good beat, when a robot hesitates before following an order and the humans around it don’t notice. That’s the whole uprising premise in three seconds, and the show never returns to it.
For an episode called “The Robot Revolution”, that’s a strange omission. There’s no robot character, no defector and nobody on the machine side with a point of view, so the title subject is scenery. Compare that to how much Gridlock gets out of giving even its most incidental background figures a life. Gatwa is good as ever, but he’s given very little to do beyond explain things to Belinda, and he resolves the climax by reversing a polarity. His best moment is telling her that a piece of junk her ex bought her has got thousands of people killed, and Sethu takes it without melodrama.
The closing beat is the interesting one. The TARDIS can’t get Belinda back to 24 May 2025, and every attempt fails. That’s a clean, specific arc, better than a mystery about parentage, and it gives the series an actual goal instead of another question. After two years of arcs built on withheld information, a run with a concrete objective is a genuine improvement, whatever this particular episode does with it.
Rating: 2.5/5. Not my favourite. Varada Sethu is a genuinely excellent addition and the premise underneath this is strong. The episode crams four ideas into one hour, though, wastes its robots, and resolves a planetary revolution with a reversed polarity. Belinda deserved a better first night.
