Best Kept Secret

This has nothing to do with my usual beat, but, having seen a screening of Samantha Buck's overpowering documentary Best Kept Secret, about autistic students at a Newark school, I feel compelled to draw attention to it. Nothing I've seen this year has affected me as much. Be forewarned: this is not one of those documentaries that arrange stories to manufacture a sense of uplift. It will air on PBS on Sept. 23; there is a brief but admiring review in the New York Times today.
