Have a look at many of the reviewers who have given this film 1 star - many usernames with random collection of digits at the end - click on their review history and you'll see they've submitted a small handful of reviews, all either "liberal propaganda" accusations or extremely brief reviews of politically-neutral films just to create the impression of a real user account. I guess this film touched a nerve! Overall the film gave a solid account of the workings of Cambridge Analytica, but I do agree that it was a little uncritical of the morally repugnant Brittany Kaiser. The transformation of the internet from an excellent research tool into a propaganda machine where the most reliable content is locked behind firewalls is a sad inevitability of this world. Who knows what the answer is? Switch off your devices and go for a walk, I guess.
