Great for what it is Is Bob Marley: One Love a musical biopic? I don't think so. Barring any official answer to what that is, they tend to take a deeper dive into a musical artist or band. If a film does that, then it better not be afraid to tell the truth. I'm looking at you Bohemian Rhapsody. With One Love, we take a slice of life take into Bob Marley that prefers to focus on faith, family, and the power of music as opposed to diving deep into Marley's life. Even the flashbacks relate more to the themes of the film rather than telling his backstory. With that in mind, the film is done really well.
Bob Marley was a warrior for peace, love, and Rastafarianism, and being generally positive. He never had an ego. Smartly, One Love focuses on these ideals. We see the attempt on Marley's life that stems from political unrest. This takes Marley and the audience on a journey of finding the best way to push on and spread joy. Whether home is being with your family, going to the land where your ancestors came, or back to the place where you were born, I think the film makes an argument that it's internal love. A home for Marley is definitely Jamaica and a climax in his life came when he went back to Jamaica to give the people what they needed: happiness and hope.
Those two feelings, among many others, are what I got while watching this and they stuck with me after. If you want more details with his life/family, how he got started, other events in his life, then there's always documentaries. A slight drawback is the music that rarely feels like it's happening in camera. If you want to relax with some reggae music, fun characters who have a ton of chemistry, some funny parts, and positive vibrations, then this is a great time.
