/refers to Season 1/
At present, Brits and Scandinavians (Danes and Swedes in particular) are apparently the most versatile and distinct creator of thrilling crime series; even when clichés available, there are always new angles or approaches, plus competent choice of talented performers, many without global fame. All this also applies to Fortitude, where e.g. always great Stanley Tucci, Michael Gambon, Sofie Gråbøl do not stick out too much, so there is a nice team playing and level differences are conditioned by the "goodness" of a character, not by talent (in my opinion, Gråbøl's character was not too versatile and visible).
As the plot, there were moments when I feared that events would take a too sci-fi turn, but, with the help of flashbacks, mysterious and criminal events found their satisfactory solution (well, a certain scene with flies was too much though). And the Nordic nature, wow... I have had some opportunities to experience it with my own eyes, but it is still magnificent to watch - usually not outside, but inside - as snow is beautiful, but -20 and below C are not...
All in all, another strong brick in the wall of thrilling series. And yes, combining the best from Brits and from Scandinavians can provide a meaty result as well, with inclusion of some other good actors from outside of these areas.
PS Season 2 is even catchier, due to Squaid and Stott.
