Tony Lip, a bouncer in 1962, is hired to drive pianist Don Shirley on a tour through the Deep South in the days when African Americans, forced to find alternate accommodations and services due to segregation laws below the Mason-Dixon Line, relied on a guide called The Negro Motorist Green Book.

Green Book takes audiences on an excessively smooth ride through bumpy subject matter, although Mahershala Ali and Viggo Mortensen's performances add necessary depth.

'Green Book' delves into racial prejudice, friendship, and growth through two men's journey. Viggo Mortensen and Mahershala Ali's performances are lauded, and the hopeful narrative is appreciated. However, the film is criticized for caricaturing characters, using clichés, and inauthentically depicting racial issues. Some argue it simplifies racial dynamics and perpetuates stereotypes. There is debate on whether it effectively addresses racism or offers a feel-good narrative. Despite mixed views on its theme handling, many value its message of unity and understanding.
