What is the author's style in The Interpretation of Fairy Tales by Marie-Louise von Franz?

Author Marie-Louise Von Franz was heavily influenced by psychologist/theorist Carl Jung. She adopted all of his theories about the collective unconscious and adapted them (in this volume) to the interpretation of fairy tales. In doing so, she is carrying on Jung's research and extending his legacy. Naturally, she is heavily invested in Jungian theories, and she uses these sets of theories in her work at the exclusion of other theories.
