1. [I am indebted to Mr J F Cat of this parish for this insight] Whilst it is an interesting tit-bit in terms of weird connections with people (like Bob Holness playing the saxophone on Baker Street (*) or Hedy Lamarr being the co-inventor of spread spectrum radio communication) that Alan Greenspan was one of Rand's inner circle, it is a bit [citation needed] that he running of the Fed was particularly Randian / Objectivtist, rather than just normal neo-liberalism
2. It went on about Rand's relationship with Nathaniel Branden, I suspect this was mainly because Barbara Branden was happy to witter on on camera about it, but whilst Rand was clearly bat-shit insane this isn't a particularly interesting story to occupy a large chunk of a film about someone most of the audience probably won't particularly know about. 'Hey, there's this person you haven't heard of, and she shagged a colleague with the agreement of her husband and his wife, but then went off in a huff when it turned out he was shagging someone else'. There are much better Rand stories.
3. Describing cybernetics without calling it as cybernetics is not unreasonable, but then using the term 'cybernetics' as a throw-away later seemed bizarre to me.
(*) A little known fact is that the recording was made at Oxford Zoo
