I am a huge fan of Bob Marley. I have seen every documentary, movie, blurb there is to see about him. This movie was really good. It would not appeal to a fair-weather fan who does not already know Bob's story and is expecting a birth to death storyline.
The acting by Ben-Adir Kingsley was fantastic. I enjoyed everyone, including the gentlemen who played his Elder, which gets little to no mention in any of the casting lists.
Those who don't like this movie, don't understand Bob, Reggae or Bob's message. We lost him too soon.
