Miranda is the worst possible character to date a moody artist, a combination that doesn’t produce fireworks but rather a steady drip of tediousness. The various subplots, meanwhile, range from flat to cringe inducing, with the worst still being the relationship between Miranda (Cynthia Nixon) and Che (Sara Ramirez), who enter a new phase of breakup-to-makeup crises built around the latter taping a TV pilot based on Che’s life. While the first season had Carrie (Sarah Jessica Parker) grappling with her grief arc after the sudden death of her husband, the second does feel a bit lighter, unearthing considerably less drama from her continued process of moving on. Awkward, unconvincing and only sporadically funny, the show remains a kind of streaming Frankenstein, stitched together from a jumbled assortment of parts. To those wide-eyed romantics who dared hope that a second season would fix all the things wrong with the first one of “And Just Like That…,” the “Sex and the City” sequel returns with its abundant flaws intact.
