Mainland master Jia Zhangke scales new heights with Mountains May Depart. At once an intimate drama and a decades-spanning epic that leaps from the recent past to the present to the speculative near-future, Jia's new film is an intensely moving study of how China's economic boom and the culture of materialism it has spawned has affected the bonds of family, tradition, and love.

The conflict of philosophy and machinery is only the beginning in this surprisingly deep and entertaining documentary about daily transportation.
