This is so much more than just a murder story. It's also a brilliant semi-dramatic and quite touching story about Annie, Mia and Birger's lives living in the middle of nowhere (and then some) somewhere in Sweden. The first episode I was confused but I quickly understood the method of storytelling, and I was intrigued so I kept watching. After episode 2 I was hooked. I was a bit creeped out by the realization of how difficult things were back then (1973) without access to the technology we have today, and that made me feel like this show is special from a lot of other crime stories. Some events I guessed pretty early what was going on, and other events had me surprised.
The calm but yet hostile atmosphere that was presented in ep 1 was managed throughout. I'd say this is a relaxing watch for anyone interested in fictional crime.
