The family matters and stuff outside the actual cases are pretty ordinary Finnish stuff; nothing too fancy or shiny but exactly as you'd imagine things to be. The cases themselves aren't too special either, maybe slightly over the top when it comes to local crime culture. Not saying these things don't happen here but let's say these aren't that common in regular police work in Finland.
Overall looks and feels like a Finnish police show; a bit of a low-key ordinary police work, but clearly not aimed for worldwide audience. That must have been an afterthought. Subtitles lose a lot in translation but they're still passable.
The original TV show based on the books was filed in the eighties and it also was a depiction of that day's policework.
