The Circle (2017) 5/10.
Great cast, terrible script. Preachy, overbearing story-telling destroys an interesting subject and a relevant topic. Instead of presenting both sides of the argument and opening it for debate it devolves into a predictable hum-drum thriller with all the thrills removed.
It's not that it's really bad, it's just so bland and mediocre that it really will not change your life (or your opinion) if you ever see this or not.
Rather read 1984, watch the Truman Show or Person of Interest, or just read any book (I suggest Foucault or Gramsci) about the use of information and power.
