Wow, this was really the long con. All of the science before the sales pitch is real and exciting though. "Fantastic Fungi" is a great documentary that explores lots of the same stuff, as well as "Call of the Forest: The Forgotten Wisdom of Trees". Diana Beresford-Kroeger has many other books that many of us tree folk would enjoy too. Another documentary I really got alot from is "Biggest Little Farm", focusing mainly on the importance of biodiversity and the dead end that is monoculture farming.
