I don't have the DVD, but I did get the book. I wanted a reference book with lots of pictures and examples to take out to the yard with the kids, and this fits the bill. This will be part of their homeschool education. The book is just under 500 pages with lots of glossy photos and quick summary of plant descriptors and uses. It is well organized into plant types with warnings of poison lookalikes and is well suited to a beginner like myself. Finding what is edible gets me out of the gate. Then I can look up more info, if desired. I like the idea of a book more than a DVD as an ease of access to reference material and am glad I didn't spend the extra money for the movie.
I've got these DVDs, (my wife bought them) and while the information isn't bad, it doesn't really go into much depth and the production values are very poor (think youtube home video quality). Rothkranz is like a 50 year old, hyperactive teenager and just goes around interviewing people on different sites in the USA and Canada, usually they are repeating similar information about common wild foods. The camera work is hand held, very shaky and there is often a lot of background noise and wind on the mic. Also there is very much a raw vegan slant on things, which may or may not be your thing. I did enjoy the parts with the people at the Living Center in London Ontario, who talk about permaculture concepts and forest gardening but not in any real depth (London is my hometown and was surprised that this place existed as it's mostly a bleak patch of urban sprawl surrounded by industrial farms).. Overall, I'd rate these discs as well intentioned, but poorly executed, possibly a bit of a cash grab, You'd probably be better off with a few good books on the subject for your money. Hope that's not too negative for a first post
I will suppress my every urge. But not this shameless plug:
