The North Water on BBC - a dark and gritty historical drama mini-series of five episodes - very good IMO. Starring Colin Farrell and Stephen Graham, with Tom Courtenay.
Set mainly in the Arctic, IMDB says this is the most northerly latitude at which a TV series has ever been filmed.
The fluffy seals getting shot in the face didn't really sit well with the missus.
Didn't get past the first episode.
Yes, some of the more graphic scenes (and not just the hunting) I found particularly difficult to watch - averted my eyes and even briefly FFW-ed at one point. However overall I really enjoyed it.
I read-up a bit on how they filmed it in the Arctic and the dangers that the cast and crew faced - very interesting. A lot of it is real and not extensive use of CGI.
