I am reviewing here as this is based on a true story. What is it with these guys who go into the death zone of any 8000+ meter mountain without oxygen support? What exactly are they trying to prove? Yes, I know there have been super fit mountaineers who have done it but what for especially when you want to spend some time up there. K2 takes another 2 victims. When will they learn? For heavens sakes guys and I hope amateurs and pros alike are reading this, on any expedition please take oxygen with you. How many have died up there because of mistakes like this one. Apologies for the spoilers but had to vent. Good movie but loss of life that could have been avoided.
