Doctor Who: Flux Flubs The Finale In The Supremely Unsatisfying The Vanquishers

"Doctor Who: Flux" began with such promise. There was a newfound energy, a pep in the step of this serialized experiment that suggested that showrunner Chris Chibnall would be shaking things up after two mildly disappointing seasons. Heck, there were even a few jokes! But we all should've known as soon as the final episode, "The Vanquishers," started off with the time-honored tradition of Jodie Whittaker's Doctor spending a finale getting psychically blasted by a camp villain — Chibnall is back to his own worst tendencies.

Like most of Chibnall's finales, "The Vanquishers" ended not with a bang, but with a whimper — and a whimper that still left 90% of the universe completely destroyed, if I'm reading this right. We've seen this happen over the past two seasons, and in the episodes penned by Chibnall before he stepped into the showrunner role: a story starts off strong, with more abstract ideas and ambition than it can keep a handle on, and then it just ... ends. Never has this been more clear than with "Flux," the most ambitious, most unwieldy of Chibnall's stories, which ended up cracking under too many characters and a convoluted plot that was mostly explained by a breathless Whittaker standing in the center of a room.

The Doctor ricochets back and forth between her three realities, waking in one body while the other two apparently sleep — though as we see later on this is not the case, it's just Chibnall's easy narrative tool to pick up with each storyline. Doctor No. 1 is brought back to consciousness by Azure, who monologues about their plan (something, something, destroy "all spatial objects" and free the manifestation of Time?) while Swarm playfully toys with the Doctor, disintegrating her body before reversing the effects. "You are the universe, Doctor," he says, gleefully, as the duo chuckle in anticipation of the return of their "Savior."

Despite her primary body being disintegrated over and over, the other two Doctors don't seem to be much affected — apart from Whittaker's usually breathless performance becoming a hair more breathless to show the destabilizing effects of being, you know, split three ways. The Grand Serpent enters the Lupari ship to interrogate the Doctor and to inform Karvanista the rest of his race has been killed, and he is the last surving Lupari — only the first instance of genocide in this episode that is basically breezed over, apart from Karvanista letting out a goofy mournful howl. While the Doctor is being dragged to be tortured by the Grand Serpent, Bel lies in hiding to pull off her part of the plan. Meanwhile, Jericho and Claire have been taken to Sontaran psychic command, where Sontarans have been burning humans up like fuel cells to pinpoint the location of the Flux — and thanks to Claire's special psychic powers, they are finally able to.

What's the solution to all of this? Well, it's all shockingly simple. The Flux is made out of antimatter, so what's the best way to combat it? Matter. And Diane, who comes out of nowhere in this third act, is the one with the answer: the Passengers are made of infinite matter. So the three Doctors rally the troops: taking remote control of the Lupari ships to manipulate the shields in the direction of the Passenger, sending Bel and Vinder (happily reunited in one of the nice character moments buried in this episode) off to blast away at the Sontaran ships, and waving her sonic around a lot. This all ends in the Flux getting sucked into the Passenger – negating is effects and saving the remnants of the universe, while still getting rid of those pesky Dalek and Cybermen armies (there's that aforementioned genocide that gets completely breezed past).

Meanwhile, Kate Stewart and Vinder team up to hold guns to the Grand Serpent's head and lock him on an isolated space rock, while Doctor No. 1 gets her final confrontation with Time itself on Atropos. It takes the form of Swarm, kills him and Azure, then takes the Doctor's form to warn her of her impending demise. "You can leave here but you can't outrun me... beware of the forces that mass against you, and their Master." Which gives a pretty obvious hint at the Big Bad for Whittaker's final episode.

And remarkably, everyone goes back to their normal lives extremely quickly — Dan back to crashing tours and getting turned down for that drink with Diane, leading him to happily accept the invitation to travel with the Doctor. We get a sweet, sincere moment between the Doctor and Yaz, in which the Doctor finally opens up to her after pushing her away (and literally being separated for three-plus episodes) and declares, "I want to tell you everything." The one thing she won't tell her about: the fob watch containing all the Doctor's past memories, which she hides deep in the TARDIS, never to be opened ... unless she really needs to.

And ... that's it? Apart from a few genuinely sad moments (RIP Jericho, you magnificent "scourge of scoundrels") punctuating the barrage of action and plot — and the Doctor explaining the plot — "Doctor Who: Flux" wraps up all too easily. It feels like it's missing an episode to get to this point — one that would go deeper into the lore of this physical manifestation of Time; linger longer on those genuine character moments; or give Vinder, the Grand Serpent, Bel, Karvanista, and basically all these new supporting characters more to do than just be there. And while this sudden ending can perhaps be chalked up to Covid cutting down the episode count, this is clearly a consistent problem with Chibnall's writing, and one that has kneecapped Whittaker's entire run. Like many of Chibnall's episodes, "The Vanquishers," and by extent, "Doctor Who: Flux" felt like a rough draft of a good idea, which was sketched out solely to figure out how to get from point A, to point B, to point C. What a disappointing way to end her final season, and what a low note on which to end a promising season.
