A monumental 150-minute attempt at tracking China’s cultural transition from Mao-ish uniformity to the eccentricities of Deng Xiaoping’s quasi-capitalism, Platform (1990) follows four wannabe performers from Fenyang over a long and turbulent decade (1979-1989). Unlike director Jia Zhang-ke’s excellent 1997 drama Xiao Wu, Platform has a bizarre disregard for character and narrative coherence.
