I don't know if I'd go that far, but it is very, very good.
I think they have managed to make it work for a wide range of audiences, which is a triumph. However, they tip toed around the fact that he's blatantly got ASD, presumably because he's not had a formal diagnosis? It would have been really interesting for this to be explored in more detail and would have taken the film to another level IMO.
His compulsion to do what he does is... disturbing. I admire him for his special ability, but at the same time I feel sad for him. I left feeling lucky that I have more in my life than just climbing.
I wouldn't expect to see anything like that again in my lifetime. Maybe he'll solo something else of a similar standard, but I can't see it being documented/filmed in the same way.
