This is one of two feature-length documentaries on the #8(The Roots of The Matrix) of the 10-Disc Ultimate Set. Apart from the other one, exploring philosophy, that particular DVD doesn't hold anything but links, and neither of these have subtitles. This does not go over a ton of different subjects, like one might suspect, no, they chose to make it all about a specific one, and concentrates entirely on it. This is all about A.I.(and to an extent, the symbiosis of man and machine), and they go over the development(and potential problems inherent to such), technology and more. This consists of interviews and clips of the movies as well as the Animatrix episodes. It all provides a lot of food for thought, and some may find this to be downright overwhelming. It's well-paced and informative. While this could be claimed to have a narrow focus, being the only science fiction extra in the entire release that doesn't directly relate to the trilogy or shorts(and there certainly other ideas in the franchise to delve into), there sure is plenty to talk about, and running at about an hour, this is actually quite concise. I recommend this to any fan of sci-fi, and anyone interested in the future of computers.
