From MHz Choice:

Rough. Raw. Real. This is the world of Arne Dahl, whose crime novels have been transposed to the screen in adaptations that follow the dramatic tradition of all best-selling Scandinavian thrillers. The series revolves around cases taken on by the ‘A Unit’, an elite force of officers recruited after a series of assassinations rocks Stockholm’s high society.

MHz Choice streams several seasons (from many years beginning with 2011) of this Swedish thriller.  There are 5 complete stories, one per different year. Each story consists of 2 episodes. Each Episode is about 1.5 hours long. Swedish script with English subtitles.

REVISION 1 (Feb 2021):

There are now 2 seasons available from MHz Choice.  In the second season several of the excellent first season actors are missing or have been replaced.  Season 2 is acceptable, but not (in my opinion) a good as season 1.  Season 2 is a bit more of a soap opera. Still worth watching.

ORIGINAL REVIEW:

Throughout the 5 stories the same team of detectives are together. As is usual in such productions, the personal lives of the detectives are easily as important as the mystery plots.

As powerful and as grim as the stories are, they are so well done that they are really worth watching. But you should expect blood, torture as well as some explicit sex. Many scenes involve foot or car chases.

Not only are the stories complicated, but there are many surprise turns including some endings you might not expect.

This series is so compelling that I will rate it a DO NOT MISS!
