More of a film essay - of the type pioneered by Orson Welles and Chris Marker - than a standard documentary, The Net: (The Unabomber, the LSD and the Internet) begins with the typical format and structure of a nonfiction film, and a single subject (the life and times of mail bomber Ted Kaczynski).
From that thematic springboard, The Net branches out omnidirectionally, segueing into a series of thematic riffs and variants on such marginally-related subjects as the history of cyberspace, terrorism, utopian ideals, LSD or the Central Intelligence Agency.
