The cast is fantastic, this is the type of movie that could not have possibly worked without good actors, and thankfully they got great ones here. The chemistry between them all is perfect and they convey each school pupil-type, such as jock, outsider and nerd, perfectly, but it's also very real. Most eighties movies, like Revenge of the Nerds or Porky's, exaggerate these personas, but John Hughes always made it very life like, and Judd Nelson, who I think is the highlight of this movie, is easily one of the greatest characters he's ever created.
