Great movie. I got more out of it from a psychological perspective. It really gets inside the guy's head and it's not pretty.
yeah, clearly he is not wired like a normal person--and the movie rightly focuses on that aspect of it to a large degree. I find that part fascinating as well. But I actually think it overshadows a bit what a ridiculous athletic achievement it is as well. Hard to separate the two given the nature of climbing, but it's an unreal feat.
