I saw several episodes and enjoyed them. But I lost track. They were originally shown on PBS. Somehow I lost track of it.
They’re free on Prime. Skip series 1, it’s the weakest. And since each series is a different time period and not technically related the only thing you miss is the 2 or 3 actually good jokes. Series 2 is probably my favorite, Miranda Richeradson as Queenie just kills me. I can make solid arguments that 3 (finally getting Hugh Laurie on full time to work with Stephen Fry) and 4 are better. But I love Queenie.
