We’re suckers for great documentaries, and there’s no shortage of them right now. What’s amazing is these films are not only fascinating and beautiful, but they create actual change. Just think about what’s caught our attention over the years: 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 got 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.
