From the official Cannes program:
      
        "A city is ravaged by an epidemic of instant "white blindness". Those 
        first afflicted are quarantined by the authorities in an abandoned 
        mental hospital where the newly created "society of the blind" quickly 
        breaks down. Criminals and the physically powerful prey upon the weak, 
        hording the meager food rations and committing horrific acts. There is 
        however one eyewitness to the nightmare. A woman whose sight is 
        unaffected by the plague follows her afflicted husband to quarantine. 
        There, keeping her sight a secret, she guides seven strangers who have 
        become, in essence, a family. She leads them out of quarantine and onto 
        the ravaged streets of the city, which has seen all vestiges of 
        civilization crumble. Their voyage is fraught with danger, yet their 
        survival and ultimate redemption reflect the tenacity and depth of the 
        human spirit."
      
      Summaries like that are usually submitted by representatives of the 
      film itself. Noting that, we may want to be aware that anything which 
      willfully purports to "reflect the tenacity and depth of the human spirit" 
      is probably some seriously pretentious schlock. 
      Blindness does have some leanings in that direction, but is actually a 
      thoughtful movie.
      Although the film was adapted by Don McKellar from a novel by Nobel 
      laureate Jose Saramago, this general approach to the apocalypse reminds me 
      very much of another film scripted by McKellar: Last Night. In the latter, 
      it is simply a given that the world will end tomorrow at noon. There are 
      no scientific or theological explanations offered for this phenomenon. 
      It's just a given, because the author wants to focus entirely on the 
      behavioral issues. What would people do on the last night of existence? 
      Would they bond? Would they eat rich food and take drugs and make love 
      non-stop? Would they take sleeping pills to pass through the final gates 
      without fear? Would they pass the time in quotidian tasks? Would the bad 
      people continue to hurt others until the very end? The premise of 
      Blindness comes from the same core of thought. It is simply not important 
      why the entire world is going blind, nor why the one woman is immune to 
      the epidemic. It just is that way. Period. Granting that premise, how 
      would people behave?
      I'd say that the work stands with the best of science/fantasy fiction 
      in that it does not begin by trying to try to push some point of view, 
      then creating a contrived story to support it, but simply sets the premise 
      and tries to figure out what kind of world we would live in if the premise 
      were true. The difference between the two can be illustrated by the 
      difference between the book version of Children of Men and the film 
      version. The book started with this premise: "What would happen to a world 
      without children? What would the world be like 20 years after the last 
      birth? 40? 60?" From that origin, the author tried to picture a world 
      without youth:  the services neglected for the lack of strong backs, the 
      lack of planning for the future, the poignantly deserted playgrounds and 
      schools, the increase of religious cults, the gradually increasing ratio 
      of women to men, etc. That hypothetical world did not become particularly 
      violent because violence derives mostly from the recklessness and 
      testosterone of young males, and there were none. On the other hand, the 
      movie version started with this premise: "Bush sucks. Oh, yeah, and 
      there's no more kids." From there, it was lost because it was forced to 
      abandon the first rule of thoughtful science fiction: pose the "what if" 
      question, then try to answer it as honestly as possible, with the ultimate 
      purpose being to study how human nature adapts to or is affected by 
      unusual or extreme conditions. We don't need science fiction to tell us 
      what would happen if Bush sucked. We saw it under actual laboratory 
      conditions.
      By the way, I liked the movie version of Children of God. It was an 
      interesting movie, excellent in many, many ways. I liked the story, but it 
      had almost nothing to do with the original premise about the lack of 
      children. It was a good film, but bad science fiction - because it made no 
      effort to stay true to its premise. It did not really try to picture what 
      the world would be like without young men (and the young women they fight 
      over.)
      From that perspective, Blindness is not as good a movie as Children of 
      God, but it is better science fiction. The world it pictures is very much 
      like the world we might live in if everyone suddenly went blind. In one 
      small corner, the isolated hospital ward of the first few victims, society 
      degenerates into brutality. In the real world, given the premise, that 
      sort of micro-society would certainly emerge in some confined places. 
      Jails, for example. In contrast, the streets outside are not filled with 
      brutality, but simply sadness, chaos, and desperation. People wander in 
      search of food and shelter and a proper toilet. Vital services are 
      neglected.
      The scenes in the contamination ward are claustrophobic and painful to 
      watch, but the movie is very different after the escape from that ward. 
      The scenes on the streets of the city are thoughtfully constructed. Sure, 
      life is bad on the streets, but it's not entirely without hope. People 
      take joy where they can - exulting, for example, in a warm summer rain 
      which allows them to bathe and gather drinking water. The small "family" 
      that becomes our anchor in the film finds a modicum of peace and even gets 
      to celebrate Thanksgiving - and they truly believe there are things to be 
      thankful for, even in those black times. And the ending even offers a ray 
      of cautious optimism.
