“Bob Marley: One Love” (**1/2 out of four) was a nicely textured but frustratingly one-note biographical drama about reggae legend Bob Marley (Kingsley Ben-Adir) set during his rise to fame in 1976-1978 when he was striving for musical stardom and world unity. Best thing about the film is Adir who is charismatic and compelling in the lead role but film is too slight and superficial and doesn’t tell you anything about Marley and his childhood and pre-fame story. At the very end, you see the real Bob Marley in documentary footage. You might leave the film still wanting to see a biography about him.
