'The Writer's Journey' (TWJ) came to me highly recommended.... Perhaps this was why I was so disappointed: I was expecting more than the book could ever deliver.
In essence, TWJ is a distillation of Joseph Campbell's 'Hero with 1000 Faces' combined with 'readings' of various films. However, instead of elucidating Campbell's work Vogler has merely reduced his source material to the level of formula. The result lacks substance; tries to fit the theory to the films rather than vice versa; and is often ponderous & pretentious.
Vogler is also a rather careless writer. The book is littered with unnecessary mistakes: Vogler's assertion that Daedalus helped create the Minotaur (p.50) when actually he only built the labyrinth that housed the beast; or James Bond's deactivation of the bomb in 'Goldfinger' (p.205) -it is actually disarmed by Felix Leiter... these are just a couple of examples in a book endemic with inaccuracy.
On the positive side, Vogler's model for reading 'hero texts' can throw up some surprises: trying watching 'Saving Private Ryan' in the light of TWJ and you will realise that the true hero of the movie is not Private Ryan, nor Cpt. Miller (the Tom Hanks character) but actually Private Opheim - the translator.
Overall though I must once again state my disappointment with TWJ(inspite of wanting to like it). Apparently it started life as a 7 page memo to Hollywood studios. Perhaps it should have stayed just that: a 7 page memo! If you are really looking for a book that deals the principles of myth and the hero, may I strongly suggest Vogler's inspiration: 'The Hero with a 1000 Faces'. It is a much more rich and rewarding text and one that does not disappoint.
