Devine's book is superb. The best book that I have come across on the topic of Vietnam (concerning film and history). In fact my Sr. Thesis was on the similar topic of Hollywood's Vietnam War films, and Devine's book was one of my main sources of information, context, and critique. He really covers EVERYTHING. Obviously I had to limit what i was covering in my thesis, but there is no shortage of information in Devine's book.
While writing a film critique for an independent study course on Problem Films of the 1970s i looked into Devine's book again, and found that a 1968 film (Targets by Peter Bogdonovich) fits the profile of a deranged Vietnam Veteran flick. I never stop learning from this guy!! As a film studies/history student, this book is considered by me to be one of the very best. I strongly reccomend it!
