We’re suckers for great documentaries, and there’s no shortage of them right now. From incredible true-crime podcasts (sup, Serial!) to the latest Herzog masterpiece, Lo and Behold, this really is the golden age of documentary. These films are not only fascinating and beautiful, but they’re creating actual change. Recently Brendan Dassey, one of the subjects of the documentary series Making a Murderer, was released from prison after more than a decade. (He was supposed to serve a life sentence.) Serial’s Adnan Syed is getting a new trial. That’s part of what’s so addicting about the form. These stories make a real difference. They throw their weight around.
