Rich Hill was the big winner at this year's Sundance in the U.S. Documentary competition, and it's easy to see why. An affectionate, judgement-free portrait of three teens living in middle-of-nowhere Missouri, the film can easily play on liberal sympathies: Liking Rich Hill is akin to agreeing with its thesis that the poor are people, too. But, as I discovered, the movie cuts much deeper than that. My review is up at Paste.
