I couldn't come even close to understanding how beautiful it might be to see the walk actually take place, even through still photos, until seeing it for myself...it's hard to explain, but when you see how it happened and all the obstacles overcome and listen to the participants talk about it, it feels like a completely pure occurrence, there was absolutely nothing contrived about the passion and commitment of the participants, the joy they got, the suspense preceding the accomplishment, etc. The absurdity that these people put so much dedication and planning into something that seems so frivolous, and that it created so much sincere passion and happiness, somehow makes it resonate even more. Like somehow by the end of it I was completely sold on their conviction that the towers were built just for Petit. Just totally gripping stuff, best movie I've seen in a long time.
