It's an interesting story, but there's 15 minutes of useful content in the story; the remaining ninety minutes is pure filler. As you're watching, whenever you feel "god we get it, you've already said this a dozen times" jump forward 20 min -- you won't miss anything.

I have nothing to say beyond that. Hopefully IMDB won't force me to pad this reviews with vast amounts of filler!

As of October, 2017 - a few months after the premier of this documentary - Herbalife stock price peacefully sits at ~67 USD. I just wanted to start the review with this statement to let everyone know the company is still well and thriving. None should look at this production as the documentary that exposes the dirty cheats that may run a corporation bankrupt or earn them the most thorough federal investigations of all time. My law teacher once told me: everyday people think that courts provide justice for the mass, but it isn't true. What they provide is law. This applies to Herbalife a lot: the way an MLM company operates is clearly unfair and unjust, but none was able to prove so far that it is completely against the law. There may be illegal operations behind the curtain we don't know of yet or 'Betting on Zero' was unable to bring to light, but as far as they are considered clean by the regulators, they go on.

However I must praise the documentary for the financial approach. It gives very good explanation on basic terms like shorting, provides a good view of the hedge fund world and reveals why the efficient market theory is far-far away from reality. So in case you want to be the next George Soros, this is a must-watch for you. If you are looking for a documentary where the little men fight to get revenge on big money, then just skip this - Mexican immigrants praying with attorneys will hardly provide you any useful information.

Writer/director Ted Braun follows controversial hedge fund titan Bill Ackman as he puts a billion dollars on the line in his crusade to expose Herbalife as the largest pyramid scheme in history.

This is just about as perfect as a documentary can get. The very moment I was introduced to Herbalife in the early 2000s, I knew it was a pyramid scheme. But obviously others do not see that, as the business continued to be profitable and thriving.

This documentary not only explores the pyramid nature of the business, but explains how people fall for it. In some cases, it is because they are unsophisticated immigrants. Other times, they had the business misrepresented to them. But it is not just stupid or ignorant people who fall for it.

Without giving anything away, this story will have you cheering on Ackman. He may be one of the very few Wall Street investors who is actually hoping the little guy will win.
