The Movies That Matter Festival just ended, and this edition reminded me why I love documentaries and why I write about them. I had a week of films and debates, and I feel I got some new insights and ideas and also some new questions. And that’s great because this is what documentaries do, they open up the world a bit more, one film at a time, and challenge our emotions and knowledge. So here are some thoughts and feelings from and about the festival, fresh from the oven.
