This film is worth watching but there are a lot of confusing parts. I never understood why the story of the Italian climber from 1954 was included. I didn't have trouble with the back and forth in the past and present, but I was very confused by who was the real person and who was the actor portraying them. It would have been good if they had explained that in the beginning; it would have made the whole thing easier to follow. Honestly, if I had not just finished a podcast on this tragedy, I'm not sure I would have been able to follow along with the film.
