SERIES PREMIERE: This series has a very amusing concept: transplant Real Housewives-type spoiled brats into a Downton Abbey-era setting. And it still might gel into a strong comedy, but in tonight’s pilot, the tantrum-throwing Bellacourt girls (played by Riki Lindhome from Garfunkel and Oates and Natasha Leggero), striving for attention in 1902 Rhode Island, are too exaggerated to be the center of a comedy. Others around them, though, strike just the right tone, including Michael Ian Black as the butler and Christina Hendricks, straight from Mad Men, as the new, immediately dehumanized maid. The show is different enough to sample, but it has to find its comic center quickly in order to earn repeated visits. Right now, Hendricks is the most realistic and sympathetic character, and one of the most persuasive reasons to give Another Period another chance.
