I think it's pretty certain that Albert Einstein did not say "If bees were to disappear from the globe, mankind would only have four years to live."
That's a bit emblematic of my feelings about this documentary. It's filled with a lot of stunning bee photography and genuinely engaging and weird facts about bees ... people transport live bees by mail you know ... but it's also weirdly lackadaisical. It's a lot of fun if you want to stare at bees for an hour and a half.
At the end (SPOILER, I guess) a whole hive of bees just ups and leaves, and their beekeeper can't do anything about it. That's awesome.
