The first "review" is actually filled with so many lies that I think they may have watched a different documentary and confused it with this one because virtually everything they say is false. In fact, the film makers go out of their way to talk to SEVERAL people in favor of medical marijuana who provide a very compelling argument as to why it should be legal. In no way does is it come across as "government propaganda" that demonizes users/growers and make marijuana out to be an overtly evil drug. The second "review" doesn't even discuss the documentary and is nothing more than a political rant.
I actually watched this CNBC special and found it to be a good primer but too short and superficial to properly cover the controversy in-depth. The first half of the doc discusses attempts by law enforcement to shut down grow houses in the Florida suburbs and also shows a site in the Nevada desert where armed Mexican nationals were growing pot and were surprised by some biologists who were in the wrong place at the wrong time. It ultimately focuses on medical marijuana and the case of Charles Lynch (owner of a medical marijuana dispensary in Morro Bay, CA) and the tricky legal problems arising from state laws being at odds with federal laws regarding the sales of marijuana. 4/10
