A poor talented young hick is far too naive and trusting. His agent knowing this about him takes advantage of this situation. The agent couldn't care less that the kid's talent is being wasted or not, and thus, going "for the money", puts the kid in one lousy movie after another insuring this wasting of his talent. The kid begins to vegetate, surrounds himself with Yes-men and Hangers-on, and to escape the feeling of all this pressure, starts "self-medicating", which usually doesn't end happily, and it doesn't.

How do ya like my movie treatise, Mr. Spielberg? I only wish I could take credit for it's originality.
