The Breakfast Club is a movie that brings together 5 students, all belonging to different cliques; the jocks, the brains, the criminals, the princesses and the basket-cases. At the start of the film, the 5 students seem so different but they all find out amongst themselves they have something in common which leads them to their own clique: THE BREAKFAST CLUB. At the end of the day they all come to understand each other and accept each other as well as them selves.
It's important to be accepting and to feel accepted. The Breakfast Club is a film that explores that importance from a high-school level. By having the story set at a school it enables this idea to be expressed through means of different characters that can be easily related to. Each stereotype has lost their sense of acceptance because of the troubles they go through at home making them feel 'unloved'. They each develop their own persona because of this, building walls and bridges in search for acceptance. But it not until they all find this common ground at which they all become accepting of each other. By the end of the film, each character feels not only like they've made new friends, but feel more complete as they've now discovered the importance of acceptance.
