Each year, 60,000 people from around the globe gather in a dusty windswept Nevada desert to build a temporary city, collaborating on large-scale art and partying for a week before burning a giant effigy in a ritual frenzy.

You have the anti-Wall Street vibe, the "gift economy" focus. Take this versus the millionaire CEOs who get involved and it is quite the walking contradiction. The anti-corporate Burning Man is itself basically funded by corporations.

I only knew of this festival indirectly, but now I see what goes on in the board room and in the field. Wow, what a spectacle!

I had heard of Burning Man over the years, but never paid it much attention. As do many people, I just assumed that it was mainly a gathering of ex-hippies to get together to take drugs and have sex. This movie disabused me of that idea. I was impressed with the dedication of most participants to provide creative works of art, some of them quite stunning. I was taken with the one sculpture of a female form that was transparent and could be lighted from the inside. I think that ultimately became a public sculpture.

Another sequence detailed the creation of a large 12' metal heart that had metal scales that allowed people to enter the inside. The amount of work and skill that went into that I am thinking exemplified what went into each of the hundreds of projects. There were a lot of fun projects shown as well, like a metal-framed snail that motored around, and a large ship. Lights and sounds abound as well as every imaginable dress (or lack thereof).

This is no trivial festival. The 2012 Burning Man, filmed here, drew over 60,000 participants. Assembling that many people without total chaos, especially in an environment encouraging free expression, is a testament to the skills of the organizers and the quality of the participants. As shown, there were five people working full time throughout the year to organize this, as well as hundreds of volunteers. There were some behind the scenes frictions noted, but nothing of significance when considering the scope of this festival.

The highlight is of course the burning of the figure that the festival takes its name from. With sixty thousand people surrounding the man at night the light show, fireworks, and the ultimate burning came through as a spectacular event. The reaction must be primitive, dating to cavemen dancing around fires. I can hardly imagine how powerful the actual experience was for those who were there. Trying to understand the significance of having put such great effort into constructing the man only to burn it caused me to scratch my head a bit. I suppose it is meant to illustrate the transience of existence and all physical things. Maybe the effort to provide 60,000 people with a memorable experience is reason enough.

There are ten principles that underpin this festival. The two that I find most interesting are the ban on money and commercialization and leaving the desert in as good or better shape after the festival as it was before.

The film quality and sound of the movie are good.

I am sure that trying to capture more than a small taste of this event is impossible, but I think I got enough of a flavor of it to be able to counter anyone who might try to denigrate it.

Burning Man is about freedom, lack of boundaries, openness, that spirit of the 60s, 70s, 80s, and 90s that had more to do with the Dead Kennedy's and Seattle than LA Law and Washington DC. It's truly about art as art not commerce.

Can the unfettered human spirit be captured on film? It would take an extraordinary documentary to even come close: it needs Fellini or Russell as director - what we get is the PBS version - it's not only highly sanitized, as in just too sanitized, it's clearly unclear about who its selling too - it is seriously tepid and works as an historical record but little else - we got a good sense that putting portaloos up in the desert is hard - but little else.

Really its fault lies in picking story lines - if ever there was a great film to be made just by pointing the camera and letting go its this one - seeing the office workings, the planning committee, and then, frankly censored, rather than edited, moments is not what should be up there.

Spark is good publicity for Burning Man by letting you know its there, but this like Taking Woodstock totally misses what freedom is about and chooses instead to box in, and entrap, and just about diminishes the spirit.

There is a great film waiting to be made - and it should be way more unviewable. shockingly joyful, and just plain good old-fashioned anarchic than this - talking heads and modesty doth not a Burning Man make.
