Joanne and I recently finished Beforeigners
It's a mismatched Cop Buddy Nordic Noir / Scandi Thriller with a novel world building twist.
Given the initial premise, they play it pretty much straight, although it does allow them to have some fun with political correctness and multiculturalism in the world they have built.
"And in the Tjuvholmen case, one of the main investigators is actually a true Viking.The criticism is unjustified.We have a policy on this show that we avoid using the V-word.- The V-word? - We prefer "of Norse descent".Right.Of course.My apologies"
We enjoyed it.

Similarly, Lars is shocked to find that his Stone Age neighbor lets his grade school son watch Game of Thrones, because who doesn't like violence and naked women?
From the portmanteau Title to the linguistic stylings of the characters, plenty of depth to drag you into it.
