Now I know what you must be thinking, what is a Disney/Pixar film doing in this list? WALL-E was the first Disney film that ever explored a very interesting idea, what happens when the Earth gets used up? The answer, of course, is space as it usually is in science fiction films. The big difference with this story is that it is told through the eyes of a simple robot named WALL-E. We follow the amazing adventure from deserted and hopeless Earth into the vastness of space where WALL-E meets new friends and uncovers the truth behind why everyone has left the planet. This film also explores the unfortunately true side of what technology has done to the health of the human population and how that may become more of a problem in the future.
