I think that the point of the story is not really about how often Holden complains but what and how he complains.
To me a great companion to this story is The Great Gatsby. On the surface the characters are shallow and annoyingly coy with their intentions. They seem to have no point - hell their lives are pointless, soaked in apathy and liquor.
Underneath all that is fear. Fear of rejection, fear of the unknown, fear of failure, and fear of oneself. I always felt bad for Holden because underneath his tough and bitter facade is a child alone in a world that cares nothing for him.
