These are very quickly bashed out over/reviews. Please excuse missed details, etc. But new Black Mirror is something specially to be noted down! The episode order was certainly cathartic, making us work through the rough to finish with the fun...
1 - Common People - Depressing satire of predatory subscription models. Like, "Brain River" maybe a reference to Microsoft's digital river (torrenting Windows updates between users to save on server cost, etc). Also degenerate live streaming taken to a depressing low of basically crowd sourcing self torture porn. Talking to extreme the unhealthy practices of being a 'channel', eg multi-day 'subathons' that Twitch game streamers run, at the shallow end.
Some on r/cfs (Reddit) said they were somewhat triggered by the portrayal of the wife, choosing to end her life due to being exhausted all the time, with long unrefreshing sleep and continually loosing bodily control (with forced adverts channelled *through* her). Given that this depressing quality-of-life is still better than theirs, with this living torture disease.
2 - Beté Noir - A dark side of multiverse transitioning, a bit like "Everything Everywhere All at Once". The ultimate for revenge manipulation and gaslighting. Of course, they transition through a lot of impossible universe spaces and make no attempt to explain why their minds transfer over. 'Quantum Compiler' magic.
