I enjoyed the telling of the story about the worlds hardest Boulder problem, and the dedication that it required, including all that time. But it was a little humourless which no doubt reflects the single minded determination needed to succeed at that level. For entertainment though, I enjoyed the recent LittleCunt video and the recently rediscovered Lifetime Project. They were more inspiring to me personally but that might just be because they were by comparison punter problems.
There was a podcast interview with Nalle a year or two ago when he was still working Lappnor that was quite insightful. From memory, he said the hard climbs were basically just pulling on small crimps and there wasn't much to it beyond that. Find the smallest holds you can hold, crimp on, pull up. He gave the impression that it was basically a bit boring so I guess the film is in keeping with that.
