Dwayne “The Rock” Johnson and Kevin Hart made a movie called “Central Intelligence” (2016). I can imagine some critics enjoyed playing with the word “intelligence,” as in the movie’s lack thereof. But the story itself has depth: high school loser and homecoming king find roles reversed 20 years later as they team up in a sort-of buddy-cop flick with a complex, and cartoonishly violent, international espionage subplot. Johnson gives a great effort, but Hart’s high-pitched schtick makes me tired after about 10 minutes. It’s similar to my feelings toward Melissa McCarthy, who, ironically, has a funny (and blessedly brief) cameo.
