Lo and Behold: Reveries of the Connected World review – Herzog's wild ride through the web

With interviewees ranging from Elon Musk to a gaming addict, Werner Herzog presents the web in all its wildness and utopian potential in this dizzying documentary

If all the data transmitted online for only one day was burned on to CDs, the pile would stretched to Mars and back. If a directory of people on the internet - like the one that existed when it was in its nascent form - was to be published, it would be 72 miles thick. There's a young scientist who's trying to create a robot that's better at football than Christiano Ronaldo or Leo Messi.

These are just a few of the things Werner Herzog fixes his critical eye upon during Lo and Behold: Reveries of the Connected World, a quizzical look into the seemingly arcane worlds of the web and tech.
