I thought it was the best documentary I've ever seen. I've been a huge fan of Jimmy Chin ever since I saw Meru, which was the only other documentary I've seen that I thought was as good as Free Solo. I climb―not a huge amount, but enough to feel like I have some clue of how insanely difficult that must have been, both mentally and physically.
I do think that they overdid the significance of his relationship with his girlfriend (not that their relationship isn't significant, it just felt like the story of the climb was overshadowed by the story of their relationship, which seemed backwards).
I'm really curious to see what Alex does now. He made it sound at the end of the film like he might be backing off from pushing the limits of free soloing. I wouldn't be at all surprised if after completing the climb of El Cap that he'd been working towards for so many years, he experienced what thru-hikers call post trail depression -- in case anyone hasn't heard that term before, it's the depression that often sets in when you succeed at something that's been your primary goal/motivator for a really long time. I've experienced this on a couple of trips I've taken, and those were only a couple of months long each, so I can imagine it might be incredibly strong when you finish a decade-long project. I can't imagine Alex just sitting around and enjoying life "at home"―he's been a climbing dirtbag (that is not at all meant as an insult) for way too long to start living a normal-ish life.
What do you all think he's going to throw himself into next?
