This is much better than any of the adaptations of Henning Mankell's Wallander books that I have seen. Jonas Karlsson makes a formidable appearance here and some of the other ones are also good. There are though a few pieces of dialogue which aren't aren't up to par as in most Swedish films. I don't know why, maybe Swedish scriptwriters can't get the right feel for the language.
My only objection is the setting of the story. It is supposed to be set in Jämtland, but is obviously set around Trollhättan and Vargön which doesn't make it very plausible for a Swede. The story is very interesting and involves a Jewish revenger and a Nazi network in Sweden. I think it is a well crafted work of one of Mankell's best books.
