I read the whole script of the breakfast club. I think it sends a strong message about stereo types. You see a lot of traits of each stero type the nerd, the jock, the freak, the popular girl, and the criminal. But each has a trait that makes them a bit less like that. You also see them bond in detention.
In this play they have a common enemy, the principal. Because of this you see how five totally different people could form real bonds with eachother. You see it most in the scene after bender shuts the door. The prisipal comes in and asks what happened and even though they all hate him they cover for him. As they are locked in a room together they start to learn more about eachother and each others problems. They discover that even though on the surface the jock and the popular girl seem like they have it made they both actually struggle with a lot. Also that the nerds biggest bully is himself and his parents and that he is actually strong when it comes to people. However I didn't find any thing out of the ordinary with the freak and the criminal. They stay very typical through out the whole movie. Yes they are very well developed characters but I don't feel that they stray too far from their stero type.
Overall I think that the play does a good job of demonstrating stero types and how they can change and not be as they seem
