I really liked it.
I had a larger conspiracy in mind but this felt much more consistent. It was always essentially a small family drama that exploded rather than a worldwide conspiracy. Vagn being the killer felt just about right.
I liked how it ended with Troels and Lund having their integrity put to the test and Lund seemingly coming out better. Theis killing Vagn was a great callback to Rehman - and it was done quite well, bit Se7en-like.
Finally, Rie's replacement was ludicrously beautiful.
