I’d seen this before but just had the pleasure of listening to it again (there’s no real need to be looking at it the whole time). From back in the days when Horizon was something really worth watching a lesson in how quite often less is more. No cut scenes, no fancy graphics, no standing on top of mountains marvelling at nothing in particular. Just forty-odd minutes of a man sat in a chair talking about how he sees the world to an unseen interviewer.

Of course, it probably helps that the man in the chair is Richard Feynman, but still.
