The true star is the Greenland setting. Breath-taking scenery.
I can't really understand the negative reviews. There may be issues with use of language, but subtitles were good enough to follow what was happening. Plenty of plots twists and story lines and kept the pace over 10 episodes.
The political state of Greenland was brought sharply into focus (like an episode of Borgen some years ago).
Anyway, I enjoyed it and would watch a second series.
