I watched “The Inventor: Out for Blood in Silicon Valley" by Alex Gibney. It's the story of Elizabeth Holmes and Theranos.
It's very, very well done..as is the case for most of his documentaries.
I couldn't help but think of another Silicon Valley huckster while I watched. It's interesting...these people use the same catch-phrases, micro-manage the same, say the same stuff about their critics and competitors, etc. Lots of similarities.
Overall....definitely worth watching.
