It's an Ukrainian tv series, maybe a little bit formulaic but the relationships are interesting and it moves along at a good pace. It reminds me a little bit of Lie to Me, in as much as the protagonist is quirky, grumpy man with an unique skill set, in this case an analytical sense of smell, which he contracts out to the police force, and a complicated family life.
I am a bit surprised that there are apparently only two types of Ukranian dwelling, either huge, high-ceilinged, modern, minimalist, steel and glass houses/penthouses or a dingy, tenement flat in an 18th century building, faded glamour on the outside and missing bits of plaster on the inside.
It's pretty humourous, which I didn't expect from a former Eastern bloc country.
