well...
first off, I have tried to explain a bit of why Burning Man is spiritual to me here:

As for the show, I was impressed. And I thought it was funny. It did not make fun of Burning Man. It *poked* fun of certain aspects, teased some people, but mostly, it showed respect and showed much more than boobies and crazies on drugs.
I'm happily surprised. The best mainstream portrayal to date.
