Just finished this, absolutely brilliant series. Very eerie and atmospheric with some great performances, Jared Harris especially and the guy who played Hickey. Going to read the book now I think.
Thought it was a bit like The Thing (1982 sci-fi/horror classic set in the Antarctic for younger viewers) set 200 years ago during Navy expedition to chart the North West passage round the Arctic.
One of the best TV series I have seen recently. I really was struck by just how desolate the landscape was during the whole thing, nice to look at maybe, but a different story altogether if you are stuck there.
Only minus point for me was the lack of subtitles during the conversations in Inuit in the later episodes, there were captions in the first few but not the later ones, not sure if this was deliberate.
