I subscribed to Netflix specifically because of the third series of Black Mirror, and watched all the episodes sometime before Christmas last year. I was particularly impressed by San Junipero at the time, but never got around to writing about it (I’ve let my subscription lapse, so can’t re-watch right now).
San Junipero contains a genuine humanism and compassion (not two words one would often associate with either Charlie Brooker or Black Mirror!). What I particularly liked about it was that is uses virtual reality, not as a way to escape real life, but as a way to get a second chance at it; the VR world is a medium for a real intersubjective relationship between two people, not a person and a set of algorithms pre-programmed to do whatever the consumer wants. I also liked the way it treats seriously religious/spiritual questions around uploaded personalities and souls, which is not something I think science fictions deals with often. It’s also very cleverly written, there are lots of incidental details that make sense once you realise what’s actually going on.
