I’m in the US so I’ve mostly watched US TV shows, I’ve been wanting to watch shows made by other countries as there must be some great ones that never took off in the states.
I’ve seen a few I could recommend like Alice in Borderlands (Japanese), Gangs in London (UK), Lupin (French)
Philip K. Dick’s Electric Dreams (joint UK and US production, premiered first on Channel 4)
This TV series fits this description to a T because I reckon that most people, when thinking of a sci-fi TV anthology series, would bring to mind Black Mirror.
I watched Electric Dreams shortly after finishing the latest season of Black Mirror; I found the former more enjoyable and poignant than the latter.
