Well, it ain't food. And it is dispiriting (assuming you still have spirit to lose). But it's also, arguably, a more interesting and informative exposé of rancid finance and pretentious financiers than, say, either of the recently dropped Fyre Festival docs. This one has better characters, a few of whom seem to see at least halfway through themselves, not to mention Koons, the charmed charlatan of McFarland's dreams.
A good well-crafted documentary about Art and the price of Contemporary Art. They follow different people in the art world: some artists, some art dealers and art collectors to understand the state of the current market and it gives you a good overview.
