I have seen A Beautiful Mind a great many times. It was one of my most favorite films for a long time. I loved it because of Russel Crowe's fantastic performance and the alien world Nash kept inside him. I couldn't care less about the equation of course but I understood the sentiment of giving the world something they'd cherish forever. And in the end, when they were showering him with commendation, it was as if my own achievement. I suppose I experienced that shared sentiment.
