The book was dense and repetitive. The movie is a glossy primer on it from 30,000 feet. But it is entertaining, and if you're not familiar with the themes and policy prescriptions of the book, it's a good introduction:

The most salient points are delivered by Ian Bremmer. And if I can take a victory lap, which I will, in the argument about whether current tech displaces far more jobs than it creates, and is delivering an enhanced but also dystopian future, Bremmer sides with me. He all but says, "This time it is indeed different."
The explanations of rent-seeking and how financialization has created a closed economy of speculators simply trading assets back and forth is brilliantly delivered. I've not seen those points made in a way so accessible to the average person.
A cool final note on the movie is the app through which it is viewed (for only $12) benefits theaters shut down as a result of the virus.
