I really didn’t learn anything about Bob Marley from this. Could have read the text at the beginning, listened to some songs and read the text at the end, and come out with the same experience.
Also please someone sack the Production Designers. Shockingly poor depiction of the 1970s. I even recognised specific modern London streets. And Trafalgar Square (which was a cesspit of filth before 2000) was somehow squeaky clean with a modern bus in the background. So many other films with lower budgets seem to manage to film the outside scenes well in period pieces, but this was just lazy.
