Without taking sides -- if there really would be a choice even imagining such choice -- the documentary describes. It doesn't quite tell, speak or attempt to communicate some events, personal stories of all injustice on all levels, dimensions and scales in academia, in the USA -- btw when having watched it, there's no need to detail it's the same in Europe, Asia, wherever. That became implicity obvious. And that itself is reason to argue why this documentary is excellent.
Those interest in science, getting thins done in the field of academia better watch it before setting foot on any univiersity campus. Not because the academia universe is worse than other worldly universes, the arts for instance, or so. No. Coz the same applies to the arts. Probably, well, most likely, to sports too.
But in academia, one did assume for way too long neglecting strong evidence, it can't happen given most people assuemd in that field are bright, least intelligent to some extent.
But it's not about intelligence. And that's what the documentary tells w/out telling because all it does is : it describes. As a matter of fact, it just reports. W/out taking sides as if there really would be a choice even imagining such choice ..
