Based upon the 1995 novel Ensaio Sobre a Cegueira (literally Essay on Blindness) by the Portuguese Nobel-laureate Jose Saramago, Fernando Meirelles’ adaptation of Blindness serves to demonstrate the conceptual limitations of the allegory as a narrative device. Where the book was an allegory about allegories, the film aims for the allegorical only to collapse into a film about the relationships between characters who were only ever supposed to be symbols.
