The effortless charisma of Ice Cube and Cedric the Entertainer, the headliners of the first two Barbershop movies (released in 2002 and 2004), helped keep those over-plotted comedies buoyant. Cube and Cedric are back as Calvin and Eddie in Barbershop: The Next Cut, but even their enormous appeal canโ€™t rescue the third installment in the franchise. Nor can director Malcolm D. Lee, who has overseen an impressive number of breezy productions: The Best Man (1999) and its 2013 sequel, Undercover Brother (2002), Roll Bounce (2005). Scripted by black-ish creator Kenya Barris and Tracy Oliver, The Next Cut is glutted even more than its predecessors with ancient fellas-versus-females debates, ungainly sociopolitical commentary and top-40 superstars trying to diversify their brands.

โ€œLately, weโ€™ve been having trouble,โ€ Calvin, the owner of the South Side shop that bears his name, says in voice-over in the opening montage โ€” a sunny, Earth, Wind & Fireโ€“scored paean to Chicago glories such as deep-dish pizza and Oprah, which soon turns into a disaster reel of the gun violence that has plagued the city. Calvin is determined to stay in the battle-weary neighborhood, though; to keep solvent, he has expanded his one-time all-male sanctum to include a ladiesโ€™ salon overseen by green-ringleted Angie (Regina Hall). Yet the coed space only intensifies the Mars/Venus divide: โ€œThe only man you can trust is the man upstairs,โ€ fumes stylist Bree (Margot Bingham), one of several lines suggesting a T.D. Jakes homily.

The intragender feuds are just as fractious. Bree often clashes with coworker Draya (Nicki Minaj), a weave specialist who also must contend with some serious side-eye from Terri (Eve, whose acting career was launched with the first Barbershop but may end with the third). The reigning hip-hop queen appears contractually obliged to say fleek, if only to provoke old-timer Eddieโ€™s grumpy lecture on neologisms. The smack talk is much sharper and funnier between the gray panther and One-Stop (J.B. Smoove), whose innumerable side hustles โ€” VD testing, dental work, counseling, real estate โ€” prove the freshest gags.

But the film too often relies on rote sermonizing when tackling the cityโ€™s scourge of shootings, a grave topic that The Next Cut is simply too feeble to examine with any real depth or meaning. (Though wildly uneven, last yearโ€™s Chi-Raq, directed by Leeโ€™s cousin Spike, at least pulses with unalloyed fury and pain about the metropolisโ€™ rising death toll.). After trying to keep his 14-year-old son on the straight and narrow, Calvin concludes, โ€œWe gotta fix our problems ourselves.โ€ The declaration typifies the boot-strapping conservatism that dominates all of the Barbershop movies, but, offered as a solution to an intractable problem, sounds especially glib.ย
