I have never seen a film so disarmingly profound. Yes, it's about the effects of economics on people, and the ways they make do by going on the road. But it's about something much deeper, the eggshell fragility of the life each of us experiences. There's community, there's love, there's getting along, but there's the interior life experience of the individual. The director and actor manages to get inside the character, without drama or sentimentality, not an easy thing to do. I felt as if I were her, on a journey akin to Frost's "the woods are lovely dark and deep, but I have promises to keep." But what if those promises are no longer necessary. It seems so simple, this film, but at the end you feel as if your life has changed.
