I enjoyed the Richie Hawtin documentary more than the video that is the subject of this thread (probably for one because I'm not a fan of house proper so an in-depth history of that kind of sound doesn't interest me much). I do, though, appreciate the admission/celebration of the fact that MDMA played a significant role in the rise of the club culture (rather than, for example, shying away from this fact as if it's something of which to be ashamed).
