At first this seemed like it would be an exploration of the olfactory arts and sciences, something you don't get a lot of so very interesting. The first person they interviewed talked about their loss of smell, good start. Then there's hunting for truffles, a sommelier, perfumers, ambergris hunters, lots of interesting stuff. And then the perfumer starts getting creepy about what body parts he wants to recreate in bottled form. And then you realize you are spending an awfully long time with the truffle hunting people who also start getting creepier and creepier with their admissions. And then its just over.
Held my attention while watching, afterwards realized it was not worth watching at all.
