SEASON PREMIERE: This Lisa Kudrow nonfiction series, which first appeared as a TV series on NBC, now appears on TLC, with a mix of old and new episodes. Tonight’s new one, at 9 p.m. ET, features an exploration of the family tree of Sex and the City star Cynthia Nixon, and the steps that she’s retracing take her to a Missouri prison. The old episodes, bookending it on either side, feature another Sex and the City star, Sarah Jessica Parker at 8 ET, and her real-life husband, Mathew Broderick, at 10 ET. Talk about keeping it all in the family – which, given the program, is completely appropriate.
