Of course, there isn't a focus on all the freakish wonderment that is Burning Man...that's not the point of the film. It never really was... or could *ever* do it justice if it chose to sample the art/culture/awesomeness and insanity, as one would speculate at the event. That's not how it is done at Burning Man.
Its about the infrastructure, and the effort, and the rest of the very difficult things that go on behind the scenes. And though not exclusively fun...(as a fox newscast might cover the event) its definitely fun to watch...
I enjoyed it very much and I look forward to watching it again. Especially since i saw it before going... it will be interesting to see it again after going.
