Great hack is not even a good hack as a documentary. This movie adds literally nothing to the thinking. Reading two good articles about CA will tell you more about the issue than this movie. So, if you have been living under a rock for the last decade, you might get something out of this or if you are one of those liberals who like sucking up on any and all data privacy and right bashing stuff. it is basically a glory account for a bunch of mediocre individuals who happened to have gotten themselves in the middle of this CA story and who deeply believe that this is a critical issue facing humanity (not poverty, not health or education, not dirty politics and governance, not media and corporate greed or individual greed) but data privacy and technology platforms and they are among the few brave and smart individuals who understand this and are fighting for the right of stupid, poor and gullible folks who dont understand. They seem to have zero awareness about history and politics even in recent past and think that these tech platforms (not people/voters or even politicians) are to be blamed for biased elections
