I love a good documentary. And a good documentary, like any other film genre, is hard to come by. Last year’s heavy-hitters like Blackfish and The Act Of Killing stood out in a pack of less-than-worthy non-fiction pics. This year, Citizenfour snuck up on me. As in, I hadn’t heard anything about it until I was getting alerts about its premiere at New York Film Festival. And it premiered with a bang. I’m not sure where I come down on the whole “The NSA is watching” scandal. Is it crazy in scope and lawlessness? Yes, of course. Is it impacting my life on a daily basis? Nope. Will it at some point?…
