Based on a memoir by Kim Barker, an American journalist who reported from post-9/11 Afghanistan and Pakistan, this Tina Fey vehicle isn’t as flippant as the acronym of its title might suggest. A fortysomething news writer in New York decides to shake up her humdrum life with a reporting assignment in Kabul that her boss has offered to the “unmarried and childless” in the office. Codirected by Glenn Ficarra and John Requa (Crazy, Stupid, Love
) from a script by Robert Carlock (Unbreakable Kimmy Schmidt
), the movie mixes comedy set inside the hard-partying “Kabulbubble,” as her adrenalized colleagues say, with more solemn and occasionally frightening moments outside it. The casting can be racially insensitive, such as Christopher Abbott playing a gentle Afghan bodyguard, but the questions posed about journalistic ethics, personal integrity, and the problematic high of wartime reporting are all worth considering. With Martin Freeman, Margot Robbie, and Billy Bob Thornton.
