Here in Europe, we have 2 tremendous series on tv at the moment.
From Scandinavia, The Bridge about a body found on the bridge between Sweden & Denmark
and Youtube trailer here
Really dark & gripping. So far we've had 6 of the 10 episodes.
Also really good (but much more violent) is the French Series Braquo about a police op that goes badly wrong
Braquo is on dvd Region 2 with the Bridge due out later this month. Well worth watching if you get a chance.
