Wow, positive thinking really does work. A woman, getting dumped on from all directions, finds her husband in flagrante delicto and absurdly dark comic hijinks ensue in “Breaking News in Yuba County” (2021). It’s not Shakespeare, but if “A Comedy of Errors” met “Hamlet” in small-town Kentucky… maybe not, but there’s definitely a full-on competition between cases of mistaken identity and cases of homicide. Allison Janney convincingly connives atop an ensemble of bad daughters (Awkafina), bad cops (Regina Hall) and bad sisters (Mila Kunis). If you think almost all the characters are annoying – I know I did – just be patient.
