Genius

Watching Good Will Hunting. Matt Damon's character is so smart I can't comprehend what he is saying. Why do they make geniuses talk so fast in movies? I feel like I have to be a genius to appreciate their character. As a result of me being an average human being and having an average IQ I automatically presume the character to be a cocky asshole who use their intelligence to insult others. I know they do this because geniuses typically aren't the muscular of people (ex: guy from Social Network) but it still bugs me. I gues because I envy them in a way and wish I were smart enough the degrade people using my knowledge and words, but I'm not. Oh well.
