If this show had been in English it would have reached the top of the charts. So different from other crime dramas, it focusses on the human side of things - the tiny decisions which alter the course of their lives, both in a good and a bad direction. The lack of focus on "why" and the fact that we never see the faces of the terrorists. And that a number of people end up in a better place after the terrorist event than before. There are both good and sad stories, and to a large extent the acting is 100% believable. The scene of the attack itself was so well made - at the same time elaborate but not too much - that it almost hurt. In my view one of the best DR series ever.
