I watched this even though one of the selling points of the version I saw stated that there were no "distracting" subtitles for the English parts. As I'm slowly going deaf I usually watch even UK productions in English with captions. So I'd resolved to delete if I couldn't follow the action. I needn't have worried. All of the main players using English as a second language spoke clearly and with minimal accents. In fact, the UK and USA actors were harder to follow. That's not to say the Germans, Norwegians and Walloons were expressionless. They weren't.
This was, then, well acted and casted. The board members of the multinational companies were perfect in their rôles, wardrobes and hairdos. The cops were convincing. The ecowarriors fitted the part. The backdrop of Spitsbergen was fascinating.
And the story gets its own paragraph. It was convoluted, intricate and it worked.
The subtitles for the dialogue in Norwegian, German and French were well translated.
I recommend this series.
