I find it to be the best introduction because it draws on material from economists of different major schools of thought without requiring the student to subscribe to any school in particular. He can do that because he focuses on the structure of the modern financial system, which is neglected or abstracted away in most mainstream and even heterodox economics literature. It makes it easy to recommend this course to anybody, because they can't say "I'm sorry, this is from the toilet-water school of economics, and I only listen to the bilge-water school."
