I am in no way a fan of Swedish TV series, but this is so well done, from the acting by the leading actors and the supporting staff, to the cinematography, using a perfect mix of hand cameras, drones, and tripods/cranes.
With simple tools the director, Kristian Petri, creates a thrilling story about a dying detective's last case, given to him by the doctor, who tells him he's dying, from over-weight, and over-indulgence.
The actors are very well picked, not a single of them seems to be miscast, or unbelievable. Even the smallest roles is so well cast, that I can only doff my hat, and say: 'Bravo!'
That it is a thrilling story, told fairly fast-paced, does not make it worse.
Reminds me a bit of Grand Turismo, where the main character, also an old, terminally ill, bloke, also dies in the end, the acting being just as impressive, and the unfortunate victim being an immigrant.
The rest is totally different, except we, the viewers, early on learn that the main character is terminally ill.
I you liked Gran Turismo you'll love this mini-series!
