Pleasantville and the theme of the cave

At the beginning of the film, David watches the show Pleasantville and thinks it would be the idea reality. The TV is device that shows the shadows, thus the reliance on black and white. The TV repairman is the puppet master and finds the idea person to live in his fake fantasy. Once David gets into the TV show, he finds that this reality is not so pleasant after all. Once he sees that he can share his knowledge with the citizens, he does so, despite his initial reluctance to do so. As people realise that there is more to life than pleasantly-ness, they become colored. Just as in Plato's story of the cave, the people who become enlightened are discriminated against. In the end everyone becomes colored because the TV repairman wanted to teach David and his sister a lesson. In addition to the strong images of the cave, their are other religious images, such as the story of Eve offering Adam an apple.
