The parents' guide to what's in this movie.

Positive Messages

Targeted messages are being used to change behavior on an epic scale. Those messages stoke fear and hatred, and are being used as instruments to divide for political and philosophical gain. Details how internet platforms are both complicit in and exploited to influence political outcomes. Carefully specifies how abuse of our individual data is affecting our lives -- "personal data is now the most valuable asset on earth."

Positive Role Models & Representations

Folks at the center of the film exhibit courage, determination, and a sense of urgency. They are intent upon revealing the dark side of technological advancements, and seek to protect individuals, as well as society as a whole, from the dangers of sophisticated manipulation of personal data. The "villains" of the piece attempt to rationalize their behavior, but are revealed to stealthily abuse technology for financial gain and power.  


Hate-filled, divisive images and messages appear on screens. 


Occasional expletives as expressions of frustration and anger: "f--k," "s--t."

Drinking, Drugs & Smoking

What parents need to know

Parents need to know that The Great Hack is a highly-charged documentary that exposes the advancing abuse and misuse of every internet user's personal data. The movie confirms that in our technology-driven world, behavior is being accurately predicted by those who want to change that behavior. The stakes are high. Using recent history -- "voter-profiling company" Cambridge Analytica's influence on Britain's Brexit Movement and on the 2016 election of Donald Trump -- filmmakers Karim Amer and Jehane Noujaim sound a call for action. The film contends that data rights are fundamental rights and must be protected. Viewers will hear occasional expletives, including "f--k" and "s--t." This serious treatment of complex issues may not engage any but the most mature kids.

Ends up being another political jab. Not really "groundbreaking" info here.

There's not much here we didn't already know. They try to tie this into some grand conspiracy against certain political figures. But honestly, if you... Continue reading

Fabulous and very informative

The show is quite complicated and swears twice in frustration but should not prevent someone from watching such an important documentary about our times. I regu... Continue reading

What's the story?

Focusing on the U.S. 2016 presidential election and Great Britain's Brexit campaign, THE GREAT HACK details the measures taken by political operatives to successfully manipulate internet users' opinions and, ultimately, their votes. The camera follows some significant players in the real-life drama that unfolds. David Carroll, an educator who instigated the investigation by suing Cambridge Analytica to get his personal data back, represents those who were exploited. Brittany Kaiser, formerly an executive at Cambridge, is the whistle-blower who helps tell the tale. Carole Cadwalladr is the journalist whose thorough research confirmed the facts. The camera interviews these people and follows them as their voices are heard. Alexander Nix, the face of Cambridge Analytica, refuses to cooperate, but his presence on film and his words are crucial to the storytelling. Most compelling are the hate-filled, relentless, divisive images and messages that appear on screens. 

Is it any good?

In this eye-opening, well-executed documentary, the filmmakers meet the challenge of blending complex tech information with heightening drama. Plus, there's plenty of "rooting interest." The thing is, in The Great Hack we end up rooting for ourselves, and the long odds of not being one of the fooled, the foiled, and the exploited, unmindful victims of "psy-ops" warfare. The villains here are those who believe it's okay to call their business model "a behavior change agency" and the people who hire them. The protagonists are the people fighting back.

Could the film be called partisan? It is and it isn't. In this piece, conservative ideologues are the bad guys. One fact revealed here is that there were 5.9 million visual ads on Facebook on behalf of Donald Trump's election, and 66,000 for Hillary Clinton. That won't always be the case. The internet -- originally envisioned as the means to a wonderful, connected world -- is suffering from growing pains, and until the same folks who dreamed it up and developed it can find a way to control its excesses and abuses, we're all in danger of becoming what this film and these companies call "the persuadables."
