Discussion about the movie blindness

I liked the movie and something that I've learned from it was that people with or without eyesight will always do the wrong thing. Instead of them coming up with some great ideas in the ward on how to distribute the food and making people feeling safe and comfortable, instead they wanted to take supremacy and abuse women in exchange for food. I liked how the movie was in a good speed but i guess the only thing that had me a little confused was that there was no resolution to the movie. I don't know if the rest of the population recovered their eyesight or if the lady stayed with older man.
