This "documentary" is poorly made and promotes baseless conspiracy theories. I saw the same stock footage of kids running through a field multiple times. I guess a $100k budget meant they couldn't find real kids to film when discussing education policies in Pennsylvania.
The "documentary" recycles debunked claims about voter fraud (like more votes than voters, a claim that Mastriano -- the "hero" in the film -- made that was swiftly debunked because he incorrectly counted the primary votes with the general election votes). It also gives a platform for conspiracy theorists who continue to get exposed for being QAnon followers, 9/11 deniers, and just generally odd.
I wish I got my time back from watching this documentary and spent it watching Borat a few times.
