This is the second recent documentary about bees and beekeeping that i've seen and reviewed, the other being Vanishing of the Bees
. As you might expect, there are lots of overlaps between the two, such as the appearance in both of biodynamic beekeeper Gunther Hauk and of Michael Pollan, a leading critic of corporate food systems and factory farming. Both films target monoculture farming and associated practices, including pesticide use, as root causes of the "colony collapse disorder" which has become a major threat to bee populations in the past decade or so. Both regard the plight of the bees as a "canary in the coal mine" which should warn us that our own health is endangered by current agrobusiness practices. Both recommend that we find a healthier way to interact with bees, and give examples of better beekeeping practices. Both also delve into the cultural and spiritual aspects of beekeeping, along with its ancient and recent history.
The main difference is that Vanishing of the Bees focusses strongly on the problems of people involved in the large-scale industrial beekeeping business, who (since they can't make a living selling honey) are forced to truck hives of bees across the country to provide pollination services to the California almond industry and similar operations. Based on their point of view, that film has a strong narrative structure, tracing the course of the investigation into the cause of colony collapse disorder, and arriving near the end at a specific kind of systemic pesticide as the culprit.
Queen of the Sun has a more meandering structure which does not keep any specific subject in focus for very long, but gives more screen time to the beekeeping practices with are (in both films) presented as more healthy and natural alternatives to the conventional industrial approach. If you like this more vague and relaxed approach, it will work for you better than Vanishing of the Sun; if you like the investigative approach, you may find Queen of the Sun too rambling. But the take-home messages of the two films are so similar that if you've seen one, you won't learn very much from the other. I would certainly recommend seeing either one or the other if you care about the way we humans relate to the natural world, especially in connection with food.
