Hicks is writing a book, ostensibly for writers of action-adventure films. I feel it applies to any genre, although the examples are all taken from movies.
The book defines what an action-adventure film is and talks about different styles. It breaks the story into several parts and discusses the protagonists role and how it works.
One of the more interesting parts of the book to me was when it discussed the genre with respect to other cultures, mostly European. It talks about why their versions often fail and how they interpret the films. Although interesting, this as a minor portion of the book.
The book will be of interest to anyone interested in how the genre works or who wants to learn more.
