To tell the truth, this short film was the most difficult one to understand.
It was very interesting, but it was very hard to figure out what the film was trying to tell us.
As Kousuke said, I think the setting of the film is the future. Well, the future which we are heading for. It was pretty dark in the film and the robot didn't seem happy. These days, because of new technologies, we are harming the environment. We know that we have to take action to protect the nature, but we keep on inventing new useful things to satisfy our wants. I think the film wants to tell us that if we keep on living like this, we will come to an end of living happily.
The robot tries hard to find water to survive. We use plenty of water and we think that the environment doesn't have to do much with our lives. Though the film tells us that we need natural sources to live, and nature doesn't exist infinitely, so if human beings keep on destroying them, we human are going to have a hard time to live.
This film makes us think about the preciousness of nature, and tells us how important it is to protect them.
