I've been watching a lot of non-American TV series/miniseries in the past couple of years - many of them available on HBOMax.
There are several from Spain:
Patria (probably my favorite) is set in Basque country over a period of several years, about two women who initially were very close friends - until the husband of one is killed by separatist terrorists, one of whom may be the son of the other woman.
Foodie Love is about a guy and a woman who begin dating as a result of their mutual love of good food. The guy in the lead is played by actor Guillermo Pfening, who was the star of a pretty good gay film from several years ago called Nobody's Watching.
One Way or Another is a comedy that defies description. It's over-the-top, vulgar, garish - and a lot of fun - about two small-town young friends who reconnect a few years later and experience a bit of culture clash in modern Madrid.
30 Coins is a crazy demonic horror series that borders on camp, but the main reason I watched was because of the hottness of actor Miguel Ángel Silvestre.
Scandinavia has a number of enjoyable detective/mystery series:
Beartown involves a small downtrodden factory town, hockey culture, personal rivalries and a rape.
The Investigation is a Danish miniseries about the criminal investigation of the 2017 death of a Swedish reporter.
Before We Die - the Swedish version, not the way-inferior English remake - aired on PBS and involves the police tracking down a Croatian organized crime family, and the complications that ensure with the involvement of the son of one of the officers.
Modus, another PBS series, involves a criminal psychologist/profiler working with the police in solving a crime. The second season, partly in English, costarred Kim Cattrall as President of the U.S.
Beforeigners - the one non-crime series I've seen - is about people from different time periods popping up in present-day Norway. It's a lot of fun.
From the Middle East: Our Boys is about the kidnapping and murder of three Israeli teenagers, allegedly by Hamas. I found it pretty involving.
The Czech series Pustina (AKA Wasteland) despite the subtitles, feels kind of American. It's set in a dying factory town where the daughter of the town's feisty mayor is kidnapped, setting up a battle with the mayor and the town's coal industry.
I also like the romantic comedy series When Shall We Kiss (from Hungary), the Italian detective series Thou Shalt Not Kill, and the German-Romanian miniseries Hackerville.
And last certainly but not least, the Italian series on HBO, My Brilliant Friend.
One final comment: I really disliked the Romanian series The Silent Valley. It's about two teenage boys meeting clandestinely (and falling for each other) and then witnessing murders. It feels rushed and the ending is really unsatisfactory and (I'd argue homo-queasy). There's an American version called Eyewitness that's way more enjoyable and (despite it being convoluted at times) and which has an ending that's way more effective.
