To watch a good movie, or to read a good book, means to convince us.
Something has to happen to us. Otherwise it is not a good movie, or book.
A good story can take us on a journey to self-discovery.
In a film, or book, we are looking for the confrontation with ourselves. We undergo a stress test of our everyday methods. With the duration of the film and the immersion in its plot, you begin to learn more about yourself and your own functioning.
Effective stories have an effect because they highlight core themes of human life such as love, betrayal, loyalty, passion, aggression, heroism, fear, sadness, etc. in a vivid and dramatic way.
Admitting to the scene is getting involved with ourselves.
