Part New Chinese documentary, part Western compromise, Fan Lixin’s film takes a problem that affects millions — the massive migration of Chinese laborers from the impoverished countryside to the industrial centers — and packages it within a tidy, fully comprehensible domestic drama. Fan gradually introduces a husband and wife scrounging for tickets to Sichuan to see their teenage daughter Qin and grade school-aged son Yang, both of whom have been raised by their grandmother while Mom and Dad worked in the city. In fact, the parents moved to Guangzhao shortly after Qin was born, a major point of contention. Fan clearly intends for this family to serve as a microcosm of the larger problem of unfettered Chinese industrialization and the splitting of families it has produced. But Last Train Home becomes so enamored with its highly suspect fly-on-the-wall access to simmering familial resentments and recriminations (which eventually result in a reality TV-worthy father-daughter throw down) that much of the larger sociopolitical context is frankly lost in the shuffle. It's certainly not "boring," but neither is it particularly enlightening. The film screens as part of the HumanDocs Film Series, free and open to the public.
