Mr Chomsky didn't have any editorial or executive control[0]. What does this documentary add in substance or form that is not a rehash of his previous interviews and writing?

Until you pointed it out, I wasn't aware that Chomsky didn't write it himself. I would ordinarily find that troubling, but the script is closely based on Chomsky's previous writing. I'm confident Chomsky would have checked it carefully and would not have agreed to participate if there was anything he was unhappy about.
Mr Chomsky gives a lot of interviews. Does he always require a veto power, how would that even work?
