A "documentary", that is not only completely biased but is also full of misinformation in an attempt to turn people into skeptics and consequently will result in the detriment to families that make the mistake of believing the utter garbage that resounds from its blatant fear mongering.
In the typical anti-vaccination and GMO stance, one completely misinformed side of the argument is presented with statistics that are either untrue or manipulated to convey a causation that doesn't exist. The individuals that are interviewed are totally unqualified to discuss the matters in question (I don't recall Chiropracters being capable of talking about vaccines and GMOs) and only put forward their ridiculous arguments in a vain attempt to get money off the people they're misinforming, and the argument is totally one-sided; there is no sign of any counter argument from people who are actually capable of offering an informed opinion on the situation. The quote-unquote information offered in no way supports the idea that vaccines don't work (it is even more horrific that they think they can get away with the debunked idea they cause autism) or that GMOs are harmful, every single verified study conducted proves both of these things wrong.
When you want to research things like this, don't watch nonsensical "documentaries" like this one, and don't google 'vaccines cause autism' because you will end up on a site offering you fake information and expensive supplements that - if they don't actually cause harm - will have no benefit whatsoever. Look at verified studies, not biased accounts from people who aren't qualified to go anywhere near the realm of the topic they attempt to misinform you about.
To summarise, this movie is pure fear-mongering rubbish, and you should go elsewhere (ie to a proper study) for actual information.
