This HBO docuseries is about NXIVM, a multi-million dollar personal development coaching company whose leader was arrested for sex and human trafficking, branding his followers, and other serious crimes. New levels of insanity unwrap at every episode in a smart and engaging way: the show follows the progression of the story as it happened and makes you wait for its biggest revelations. It becomes a come-for-something-stay-for-something-else kind of deal, since even without the sex cult angle, the show dissects the manipulation tactics that led many successful people to be part of the organization, and later on to recruit others like them.
