Well-written videos.  I have my criticisms (such as the omission of discussion of deregulation, Reagan’s Keynesianism, and the fact that we have “bottom up” without anything in the way at the moment), but it plays to the intelligence of the viewer and such art is so rare, I won’t taint the experience by obsessing with trifles.  Clearly the authors lean towards Hayek, but it’s a very good framing of the basics.
