As I write this, a few days after the film's release, so far only three users have posted reviews about it on IMDb. Given that the film ends with the revelation that 1,200,000 people are on the US government's watchlist of people under surveillance, if you're contemplating adding a positive review, the first question that you have to ask yourself is: will this make me number 1,200,001? I've followed the media stories detailing the contents of the documents Snowden leaked, so that part of the film wasn't new to me, and in fact I felt some of Snowden's more serious disclosures were underexplored in the film, maybe because of their somewhat technical nature. If you're looking for a documentary that lays out in detail all the ins and outs of what the NSA is up to, this isn't it. The main strength of the film lies in its portrait of Snowden as a person. The filmmaker and other journalists basically meet Snowden in person for the first time with cameras running, and it's fascinating to watch them getting to know one another in such a highly charged, high stakes situation. Snowden is very articulate and precise, and obviously motivated by a very moral sense of right and wrong, in much the same way as Daniel Ellsberg. Whether or not you agree with Snowden, the film definitely undercuts criticism of him as being unpatriotic or mercenary. The documentary works well as an introduction to the Snowden story for those only casually aware of it, and also as a tense real world political thriller, sort of like Three Days Of The Condor come to life, but without the gunmen and Faye Dunaway. All in all, a very important film that everyone should see.
