I read that this movie got some pretty terrible reviews but i kind of enjoyed it. I'm a sucker for cop/detective movies especially ones where the main character is jaded and burnt out and the movie has a great cast - Micheal Fassbender, J.K Simmons and the beautiful Rebecca Ferguson. The story kept me interested all the way through and the Norwegian setting is pretty stunning to look at.
It felt like a TV movie in places though probably because nothing is overly flashy and the movie wasn't particularly action packed but i did enjoy the police procedural elements. It's well acted and i was invested to know what would happen next.
Also you're kept in the dark until the last 15 minutes as to who the killer is and then my reaction was "Oh, it's that guy....really?".
Not as awful as the reviews would make you believe but not a classic. If you enjoy detective thrillers i'd say check it out, you'll have a decent time.
