Leapfrogging between past and present, while deftly mixing contemporary and archival footage, "Unfinished Spaces" tells the remarkable story of how in the early 1960s Castro enlisted three visionary architects to construct a Cuban National Art Schools complex.
But before the project could be completed, Cuba's revolution became Sovietized and militarized, leading Che Guevara and others to denounce the new school's sensuous architecture and its pleasure-seeking student life as decadent and counter-revolutionary. Many additional plot turns ensue as the film examines 40-plus years of Cuban history through its singular prism.
