The episode is shot entirely in black and white, which helps establish the bleak feel of the episode. But of course it's bleak, this is Black Mirror. Then within the first two minutes, two of the three human characters in the story have their heads blown off by a hideous four-legged machine, just to further establish the tone of the story; bleak and getting bleaker. But again, this is Black Mirror. Then there is a relentless machine chasing human plot that continue to the end. A couple of other disgustingly mangled corpses are thrown in because, why not? But ultimately through fierce determination and some cleverness on the part of our 'heroine'; she defeats the machine! So, after all that, a victory! A note of triumph, or least some satisfaction at surviving! Hell no, this is Black Mirror. Because of a literal parting shot from the machine, the human has fatal implants in her that she cannot successfully cut out. So she slits her own throat. Then, one last, absurd and gratuitous trashing of the notion that anything uplifting might be gleaned from all this; it turns out the initial outing to a warehouse by our three humans, which ultimately killed them all, was to get some teddy bears. That's Black Mirror.
