The film is good, infact its one of my favourite films however its messages are weak
Self improvement is masturbation, yes true but then so is self destruction
Every single scenario in the movie is masturbation primarily because they oppose an emotion, emotions come from the ego, the ego is the processor of society.
Without society there is no ego, without the ego there is little or no emotion, without emotion self destruction or self improvement do not exist.
Society is an infinity, because it controls perception, except this perception is a mirror entity as other perceive you.
Like I said, the social mechanism is a mirror facing a mirror
