Confusing and untrue at times. I had to read about what actually happened to find out the facts after 2 hours of poorly put together interviews. Also the Serbian climber was quite selfless and died because he unclipped to let other people pass him, not to pass Skog. I don't know why they would make such a strange mistake on this detail, but it's either deliberate lying to make the story better or poor research.
At 8 a.m. climbers were finally advancing through the Bottleneck. Dren Mandić, from the Serbian team, decided to attend to his oxygen system and so unclipped from the rope to let other climbers pass. Mandić lost his balance and fell, bumping into Cecilie Skog of the Norwegian team. She was still clipped to the rope and was only knocked over. Mandić fell over 100 m down the bottleneck.
