Criterion has a 2-disc release, and DVD Journal reviews the film and Criterion's edition here. Senses of Cinema calls it "a visually hypnotic, deeply affecting story of conscience, love, and reconciliation". The New York Times says,"It is science-fiction in the formal sense of the word; in substance, it is a parable about the nature of mankind."
