I have just seen this. It was not available on amazon prime. I rented it on apple .

I can't speak to its accuracy, it is, however, sort of distressing to watch - in the sense that you know that they knew they weren't in a good spot from the off. . I find the older I get, whilst I can gloss over the artistic licence (the second take at your rifle as a mountain self destruct....... There were a couple of others..... All of which IMO were completely unnecessary)

These film moments seem to be completely secondary to the chaos / madness / insanity of being in the moment. Completely superfluous.
