Eh, as the reviewer says it does cater to fans. It's not something I would show my parents. But having said that,

Although I haven't seen it, i'm surprised everyone's first take is to not believe the public might value watching this thing theatrically. Star Wars is such a part of the lexicon of culture since 77, there's rarely anyone (born around then, and after) who isn't vaguely familiar with the general building blocks which come up in this doc. And this doc. then provides and easy segue into concepts like preservation and fan edits which they wouldn't normally be introduced to, but could potentially impact their lives. Plus people can always walk away with the idea, hey i'm not as crazy as that Jar-Jar hater. For me that makes this a perfect small theatrical run presentation.
