The photography is remarkable. The talent and determination of the climbers and crew was also admirable. But it's about 15 minutes too long. We got the message very quickly that we are watching an heroic search for a dead explorer. So don't keep hammering that into us every few minutes.
It's also redundant to keep telling us what difficulties the crew had to endure. It sounds like a rationalization to make us feel better about what turned out to be just a massive ego trip.
