Agnes Varda has a gift for brilliantly constructing films in a way that makes them seem casual and inevitable. In the breathtaking “Vagabond” we see glimpses of the final days of a woman who is disconnected from society and is living on her own in a tent. It feels like a series of vignettes, but as it progresses the threads begin to weave together in unexpected ways. A quiet, thoughtful, and tragically beautiful film.
