From Australia, there's Rake, Miss Fisher's Murder Mysteries, and The Nowhere Boys, although for that last one only the first 2 seasons.

My current Australian obsession is Bluey.

Doc Martin, Merlin from the UK.

Murdoch Mysteries earlier seasons from Canada.

I also enjoyed a few Korean drama series like Misaeng.

And this is really old from Japan, but Bayside Shakedown drama was really fun.

Other Japanese dramas I liked include Proof of the Man, Aibou, and Shinzanmono. I love Japanese police dramas and mysteries.

• Spooks
• Torchwood
• City Homicide
• Life on Mars (UK)
• Stan Lee's Lucky Man (I think this is british)
• Hudson and Rex (early seasons anyway were fun)
• Doctor Who through Peter Capaldi, though the Tenant years were the best IMO.

Probably many others I just don't recall

Der Tatortreiniger (German)

I haven't gotten very far, but I like the comedy and character interactions so far.

Philip K. Dick's Electric Dreams (joint UK and US production, premiered first on Channel 4)

great ones that never took off in the states

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.

We're on a UK/Irish police drama kick right now:

• Line of Duty
• Bloodlands
• Blue Lights

If you don't mind a bit of war history, SAS Rogue Heroes is incredible. Great look at the unit that became the British SAS, with some really good comedy thrown in. In the same vein (British war/comedy), Bluestone 42 is great too.

It's a bit old now, but I really liked Summer Snow from Japan. Also Hungry from Japan (similarly dated).

Utopia (AU) - similar vein to Parks & Rec but more bureaucracy. I love it.

There a lot of great kdrama shows. And no, I’m not talking about Squid Game. I can recommend Beyond Evil, D.P., and Moving.

• Top Gear (UK), but uhm I got some bad news for u my man.
• Taskmaster (UK)
• Mock the Week (UK), also some bad news.
• Te land, ter zee en in de lucht (NL), also some bad news.
• Takeshi's castle (JP), but basically every country had their own commentary version. Endend, but a reboot is available on prime I think.

Basically I don't watch TV anymore.

Exit (Norwegian)

Klovn, the tv show (but also the three movies they made), is a Danish Curb Your Enthusiasm style show, often much more out there and including a lot of references to bodily humour.

It might take a little while to get into but it is riotously funny at times.

I think it was on Hulu for a bit, for all you Americans.

• Slow Horses (UK/US) Gary Oldman and Kristin Scott Thomas? Yes, please!
• Broadchurch (UK)
• Glitch (AUS, first season only)
• Chef! (UK, first two seasons only)

Forgetting many others but just having first cup of coffee

Kingdom (South Korea)

Derry Girls (Ireland)

Silent Witness, Waking the Dead, Hinterland, Inspector Morse, George Gently, Vera, Poirot (the David Suchet version).

We watch a lot of detective shows.

Danger 5 from Australia: It's hilarious.

A Very Secret Service is also funny (but it's in Fr*nch)
