Good movie, but best of all time? Hardly . . .

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

This story has more twists and turns than a second-rate soap opera.

The acting in this movie is really good.

A long but engaging and extremely even-handed documentary, and it's engaging in large part because it doesn't take obvious sides. You really don't know which way things will go, nor is anyone portrayed as a purely good guy or bad guy, and different parties are given equal opportunities to speak. I liked it.

I've been interested in multi-level marketing (MLM), AKA legal pyramid schemes, for a while now, so when I heard about this film I knew I needed to watch it. There's a lot to like about it, but there's also a lot to hate. I would have loved for it to focus more on Herbalife itself and its victims. There's a decent amount of information about Herbalife (which is nothing but despicable) and a kind of sub-plot about a group of Latino immigrants who are trying to sue the company for taking advantage of their community. There would probably be more than enough going on there to make for a decent documentary, but instead it focuses too much on the stereotypical "wolf of Wall Street" opportunist (oh wait, my mistake,"activist investor") Bill Ackman and his bid to get rich(er) off of ruining Herbalife's stock. It's clear to me that he's just a sociopath himself who doesn't really care about Herbalife's victims at all, but just sees a situation to exploit for his own financial gain. On one level, I get it. It makes for a very juicy story and everybody wants a "hero" to root for. However, I would rather that hero to have been the actual underdog here, Herbalife's victims. I do think that there is a valuable lesson in the childish quibble between Ackman and his nemesis, fellow Wall Street scum Carl Icahn, about why using the stock market as an indicator of how the economy is doing is basically meaningless for the average person: in reality it's little more than a playground for the ultra-rich, men who are so out of touch with reality or basic human empathy that they put their own egos (oh, and money, did I mention money?) above everything else. It's well-made and will surely keep you entertained, but ultimately it feels hollow and left me hoping for a better documentary about MLM itself, not ego-measuring contests between reprehensible "activist investors".

The "victims" of Herbalife claim they have been taken advantage of but do not take any personal responsibility. I understand these type of companies are manipulative but you have to watch out for yourself. Our society is full of salesmen, schemes, and snakes that are after your money its not just Herbalife. Bill Ackman seems insincere to me. He has 1 billion dollars invested that Herbalife stock will go down so of course he is going to try and sell you on all the negatives. If there was any positive aspect of Herbalife it wouldn't be included in this documentary. Very one sided.

William Ackman, quietly charismatic investor and producer of Inside Job, has made a short bet on Herbalife, which he claims is a pyramid scheme benefiting the rich at the top and stealing from the poor at the bottom. Betting on Zero is the fascinating documentary about the battle between equally charismatic Herbalife CEO, William Johnson, and Ackman.The ambiguity comes on two levels: Is Johnson a con man or a brilliant business man? Is Ackman in this game to bring down the price of Herbalife's stock and cause the company to close, or is he looking to make a huge profit (he promises to spread his profit to the poor, mainly Latinos, who bought into the pyramid)? This doc is not as pro-Ackman as you might expect. By tracking him coming to a meeting like a rock star out of a black SUV and increasing skepticism about his motives, it seems to support a balanced view. Yes, Johnson has been part of a management that has made the company worth over $50 billion and many at that high level, millionaires, yet the evidence is that the need for more and more managers merely means more people in the lower levels will never make a buck.As with The Big Short and Margin Call, both about the bad mortgage game, the tension is ripe even though we know the outcome of a potentially nerdy story. However, these stories are all fraught with human drama and educational enlightenment for those of us not versed in financial language and events.These real-life stars carry the moral ambiguity of Shakespearean tragic characters, which, in this case, appear to honor and protect the consumers who buy their products. You will leave the theater with a better understanding of shorting and more than that, a wariness about door-to- door products and slick purveyors.
