Honky male actors have been making mediocre action movies for years, so I see it as a sign of gender equality that Taraji P. Henson made the incredibly mediocre “Proud Mary” (2018). It’s got two hallmarks of mediocre action cinema: Good guys with 100 percent handgun accuracy versus bad guys with 2 percent accuracy, and the Law of Unlimited Bullets. The slapped-together plot has her assassin character trying to flee a crime family, save an orphan and survive a mob war she semi-accidentally started. The title hinted that Henson might try a spin on 1970s blaxploitation films. Disposability won out.
