"This series is about how those in power have used Freud's theories to try and control the dangerous crowd in an age of mass democracy." - Adam Curtis
Again Adam Curtis teams up with the very people he purports to be criticising, to deliver a powerful subliminal message that it is people who are dangerous and not those few with real power over the many.
