Zac Efron and Robert De Niro star in a scene from the movie "Dirty Grandpa." The Catholic News Service classification is O -- morally offensive. (CNS/Lionsgate)

By Catholic News Service

Sexploitation flick featuring Robert De Niro as a libido-driven, newly widowed former Special Forces officer who has taken to Florida by his grandson (Zac Efron) for a decorous visit to Boca Raton. They wind up instead at spring break in Daytona Beach where De Niro spends most of the movie chasing a potty-mouthed coed (Aubrey Plaza) who’s mistaken him for a professor.

Director Dan Mazer and screenwriter John M. Phillips take a “let er rip” approach to the crudest of references to sexual activity and any other body function that comes to mind. Their smorgasbord of smut’s most repellant offering is a sequence that attempts to mine laughs out of the suspected sexual abuse of a child.

Strong sexual content, including full male and female nudity and coarse banter, frequent drug use, pervasive rough and crude language.

The Catholic News Service classification is O — morally offensive. The Motion Picture Association of America rating is R — restricted. Under 17 requires accompanying parent or adult guardian.
