Luther

Luther is a British crime show staring Idris Elba as a detective with issues. The plots are edgy and at times push the limits.  The supporting cast is excellent as well, especially Ruth Wilson as Alice.  Luther consists of three seasons with the promise of movies to follow.

Of all the British police shows I have seen this ranks up at the top of the list along with Sherlock.  If you like good acting and edgy police shows then this one will not disappoint.
