This movie "The Circle" was quite good example of hi-tech and extreme surveillance, they took it to new levels. (Spoiler) Even in the end they liked to make everything public as if it was a good thing for all to see. It reminded me of the content of Youtube today and other social medias that I am not part of, but I can imagine what comments people make public in them. There are similar stuff going on in the movie.
It is sort of bad movie (IMDB rating 5,3), but educational for privacy matters which it is based on mostly. At some point to the movie I thought "How to lose friends and alienate people" minus the "Circlers" of course. Just gotta wonder about the power source of those cameras they have in that movie.
