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)
Silent Witness, Waking the Dead, Hinterland, Inspector Morse, George Gently, Vera, Poirot (the David Suchet version).
We watch a lot of detective shows.
