Coming of Age
Will might know almost everything about chemistry and math, but he hasn't passed the third grade when it comes to living as an emotionally healthy adult.
In fact, Good Will Hunting is basically the story of Will learning to overcome his childhood fears and to develop as an emotional and vulnerable person so he can live a fulfilling life.
In Good Will Hunting, we learn that being smart doesn't mean a person is mature.
Good Will Hunting reminds us that you can't waste your time trying to be happy if it keeps you from achieving greatness.
