I think the second half of the movie is where its real main attraction is.
Everest base camp is a pit of garbage, The film makes one tiny reference to this when a character picks up a few items of discarded litter.
However, once they got to the top it seemed frustrating as an audience member that their ill-prepared venture wasnt foreshadowed more.
Is this perhaps the point – to feel the loss?
During their chit chats, one of the climber expressed it very beautifully: It is not the altitude, but the attitude matters.
Without these delays the climbers likely would have likely gotten back to base camp before the storm came.
Everyone in the film was care-beared, thankfully, and they had to be otherwise it would impossible to tell who you were looking at.
Before I knew this was based on a true story I had seen some trailers and thought that this was gonna be your typical stuck on a mountain disaster movie, its really not at all.
Everest makes us just say okay?
You cannot toy with its reality.
