The movie is like this story of one of the many lain back starseed from other more lain back planets who is birthed on Earth and then finds it hard to be restricted like the rest into doing the mentally-restricting social jobs in order to be seem as 'useful' to the society.
Throughout the movie, Dexter is seen taking it easy, going on holidays, using alcohol and drugs to relax. Dexter's father refers to him as a degenerate. His mother wished that he could do something to be more accomplished.
The movie shows Dexter to have much conflicts with those serious people that are opposite to him. Perhaps the Yin and Yang symbol mentioned in the film is referring to this recurring theme.
Much of Dexter and Emma's bff conversation with each other is about finding what jobs to do with their own lives and who to get it on with. The whole movie totally revolves around these 2 themes.
When Dexter finally found Emma to be his true love aka soul mate, he also found his true job to run a cafe. We know Dexter has lost something he really cherished when Emma died and he got really depressed and degenerated a while back into his younger days when he seem lost in the world.
Moral of the Movie
The movie has a message that seems to show that lain back people like Dexter who takes life more easily will make it till the end, and uptight people like Dexter's mom and Emma will get stressed quickly and die early.
