I like it when the main character is completely silent. I like it because it is a whole different perspective. Other characters discribe what you said and that is their interpertation of it instead of how you really feel. You only get the outshell and never the real complexities of the character which are shown through the actions of the character.

Its how people view the character vs how he acts. When the character talks you never get that type of view because you know what he is thinking. Its just not as interesting.
