The importance of this Edward Snowden documentary is two-fold: portraying a whistle-blower who decided to do what he believed was right, and threw his life away in the process, at the mere age of 29. More importantly, the film documents events ... as the whistle-blowing is in progress - as the film's director was the first person Snowden contacted to disclose his Earth-shattering truths. We're witnessing history unfold, as one of the most important people of the 21st century comes out, and right or wrong, tells his tale. That's a monumental event in film-making. Worth every positive review of its 97% score.
After-note: Maybe I should have left it to an expert like Godfrey Cheshire to comment on the film's significance. Make sure you read the entire review:
"... It is not an overstatement, I think, to call “Citizenfour,” Laura Poitras’ film about Edward Snowden, the movie of the century (to date). That statement is meant, first off, to suggest certain things about its relation to our collective past, present and future. No film so boldly X-rays certain crucial changes wrought upon the world, and especially America and its government, by the terrorist attacks of September 11, 2001. No film so demands to be seen by every sentient person who values his or her own freedom and privacy. No film so clearly implies actions that need to be taken to prevent the 21st century from turning into an Orwellian nightmare in which technologically-enabled tyranny is absolute and true political liberty, for all intents and purposes, nonexistent."
