Blindness 4/10.
What a horrible attempt at a movie.

Even though it featured some great actors, they didn't act. The script must have been very low budget and the director (of City of God and The Constant Gardner, 2 good movies) must have been asleep most of the time.
It's really a shame, because the concept for the movie is really great. When a infectious disease causes people to go blind, the infected are put together in an abandoned hospital. It's really interesting to see what the loss of sight does to people (walk around naked, forget about races...).
The situation becomes critical when violent power relations start to emerge.
Now the interesting thing is: there is 1 woman there who hasn't gone blind.
This would make for a great movie, and the trailer gave the illusion it was.
But alas.

The dialogs were so painful, there were major loopholes that could have been easily avoided. Bah, I'm ashamed I've seen this movie.
