I must disagree with your second point. Well written scripts, be it anime, TV-shows, movies, foreign or domestic, tell a story and have many layers of meaning. The Referential Meaning is the most obvious flat and shallow that any given story has to offer:
In the Depression, a tornado takes a girl from her family’s Kansas farm to the mythical land of Oz. After a series of adventures, she returns home.
This is nothing but a bare bones plot summary, and relies solely on the spectator’s ability to identify specific items. If you give the story a bit of thought you arrive at the Explicit Meaning:
A girl dreams of leaving home to escape her troubles. Only after she leaves does she realize how much she loves her family and friends.
This is still fairly concrete, a typical answer to the request of the ‘point’ of the story. Digging deeper and beginning to truly analyze the story you arrive at one of many Implicit Meanings:
An adolescent who must soon face the adult world yearns for a return to the simple world of childhood, but she eventually accepts the demands of growing up.
This is more abstract, and open to interpretation. It assumes something more that what is explicitly stated in the presented dialogue and visuals elements. This is the point at which the spectator can apply his or her own life philosophies and experiences to the story. If you take your analysis one step further you will find the Symptomatic Meaning:
