This century, a Scandinavian crime drama has become a sign of quality where felonies are closely related to human relation issues and harsh natural environment. Even when crimes and their solutions can be a bit "far-fetched", then characters and methods are always realistic - the policemen and their outfit do not resemble a model agency.
As I somehow watch Graven after its loose sequel Morden, I had some picture of the team members already, but it was still good to follow how people so different and with complicated nature/background can be joined to work together with the aim to solve a horrible crime. Above all, it was thanks to their leader Cege Ljung whose diplomatic skills were often impressive - in spite of personal issues back home... He was well performed by Kjell Bergqvist, but still, for me, both his character and performance were overshadowed by Göran Ragnerstam / Claes Grimme and Jens Hultén / Theo Koders, with their minimalist approach even more impressive. To add the venue and locality, diversification of the crime development - and you get a versatile drama focusing both on the crime itself and personal issues of all persons involved.
Perhaps the number of episodes and/or their length could have been smaller, but thanks to suitable mood and good acting, no blah! feeling comes up. For bigger clarity, it is still advised to watch Graven prior to Morden.
