Lo and Behold: Reveries of the Connected World review – Herzog's sombre look at the digital revolution

Werner Herzog's documentary about how the internet has changed civilisation is thorough and thoughtful, if not conclusive

This week, the prolific film-maker Werner Herzog has also released a Netflix documentary called Into the Inferno, about the terrible might of active volcanoes. Here is his second new film this year (there's a third to come, called Salt and Fire). It's another catastrophist study of a colossal force that is indifferent to humans' puny and irrelevant moral judgement. His subject is the internet and our new world of digital interconnectivity, and he takes a sombre, quite censorious line.
