I just finished watching it on NatGeo, and I'm still shaking. I'm a rock person (not a climber), and I'm still amazed how anyone can climb that stuff. I really need to get myself to Yosemite! As for the movie, incredibly well shot, the story was always moving forward, the inter-personal tension was always high, and you could easily empathize with the friends who couldn't bear to watch. Absolutely-freaking-insane.
