"If the old doesn't go, the new never comes" recites a teenager hanging out near a demolition site in the center of Chengdu, the Sichuan capital in western China. In Demolition, filmmaker J.P. Sniadecki deconstructs the transforming cityscape by befriending the migrant laborers on the site and documenting the honest, often unobserved, human interactions, yielding a wonderfully patient and revealing portrait of work and life in the shadow of progress and economic development.
