Fans
Douglas Adams (Doctor Who,
Hitchhiker in the galaxy, etc.) and generally lovers of good absurdism - will definitely like. The main thing is to endure the first couple of series. Then you get drawn in and begin to enjoy a bunch of qualitatively parodied stamps - time machines, crypto-inventors, secret military units for working with paranormal phenomena, fairy-tale worlds, evil wizards, etc. - built into American everyday life.
: there is no detective agency as such : More precisely, it appears at the end of the second season.
