This very silly show imagines Downton Abbey with the classy upper classes replaced by blithering idiots. The show is funniest in the way these rich people treat their servants, which is as considerably less than human, as when a servant is whimsically renamed "Chair" by one of her employers. The wealthy are idle and clueless, and the show loves to push the bounds of decency, with characters being horribly racist and crude humor that often cheerfully crosses over the line, as in an episode that mocks rape.
It gets away with this because it knows what it's doing. Underneath the silly, broad comedy, is a fairly sharp satire of class privilege. That combination of cheap jokes and smart comedy is, for me, irresistible.
Another Period is an absurdist comedy about a rich family of buffoons. Such extreme comedy is hit or miss, but this freshman show has really created something that makes people laugh. If it makes you laugh, it's a good comedy and this show definitely makes you laugh.
