Very good acting, but the show is slightly spoiled by lack of attention to detail.
The representation of the Arctic looks more like an early Dr Who set.
In freezing conditions nobody's breath was noticeable.
In the last episode it was strange that a group heading south in the Arctic always seemed to have the sun behind them - good for cinematographic effect, but 0/10 for realism.
Otherwise an enjoyable, often gory, watch.
