Black Mirror seems to be getting more samey, with ever-less varied stories that rely way too much on lampshading (i.e. the plot acknowledging its own silliness to avoid looking absurdly implausible).
This episode had some great ideas, but it felt like the biggest manifestation of those problems. Plus, it breaks what I took to be an unwritten rule of Black Mirror: no cross-episode continuity. The idea that all of this weird shit might be taking place in the same universe only detracted from my experience.
