This can be viewed on several levels, so it has different payoffs for viewers with varying interests. As a student of inequality with practical experience working on learning expeditions for senior executives, the scenes of Greta at varying conferences and gatherings of elites act as a crystal-clear demonstration of how elites co-opt threats to the established order by polite listening, condescending responses, and continued ignoration. As a window onto the physics of elites' closure from perturbation, this is a 5-star, as a documentary overall it is very intimate, but a bit scattered.
