Saw this yesterday in NYC, and on balance thought it was very good.
Incidentally, I think now I'm somewhat less perplexed at the box set's inclusion of otherwise baffling full-length "culture documentaries" on fan films and cosplay. I figure that these are intended as the anti-PvGL, in that they present a white-washed, one-sided, officially permissible look at the fervor and devotion that PvGL fleshes out in a more balanced way. Considering how long this doc has been featured on the festival circuit, I figure Lucasfilm wanted to address the same profound principle of SW's "participatory" appeal, without airing the legitimate grievances regarding the SE revisionism and PT brand-raep.
Oh, and I love that they included Wesley Willis doing "Jar Jar Binks." The song's best couplet: "You are a stupid bastard. You are an evil bastard."
