This story of an albino boy struggling to survive in Tanzania is harrowing to watch but also marbled with moments of transcendent beauty. Artist-turned-director Noaz Deshe’s debut feature about Alias (Hamisi Bazili), an adolescent boy struggling to survive in his native Tanzania, is in some ways the definition of challenging cinema. An extraordinary work, half magical-realist fable, half anthropological essay, marbled with moments both of transcendent beauty and dirt-poor grit.
