this movie had a strong effect on me, but i also saw more in it than just the desire to control things. the 4 subjects really reflect different aspects of life.
the lion tamer is a bit scary, in that he violently intimidates beasts. the gardener is amazingly skilled, but laments that he has no apprentice. when he dies, his 'art' will dissappear. the mole rat man describes a mammal that literally changes due to its social position (like insects), offering a scary social idea when applied to humans, who also have highly specialized social positions. the robotics researcher believes all organic things are a series of 'yes/no' sensors, and dreams of making a robot cockroach, requiring about 6 million (?) sensors. this idea is also scary when applied to humans, as if humans are souless organic computers, just a series of programmings.
all 4 subjects offer a wildly different take on the human condition, and all strike me as true. i don't give it 5 stars, because it is long and meandering, but it is definitely a great film.
