One of the things I remember most fondly about the '80s were the trend of nerd films: films like Revenge of the Nerds, Weird Science, and my fave, Real Genius where oddball, brainy outsiders were the heroes.
The end sequence of Revenge of the Nerds, culminating in an inspiring speech, is a classic. Its really about misfits and oddballs and people who just don't fit in finding their place in society and standing up for who they are. Its a message which should resonate with anyone who has ever felt different, regardless of whether one considers oneself a "nerd" or "geek" or "freak" or any other category.
