Andrew K’s review published on Letterboxd :
If you are familiar with the life of Ali, you will probably be bored with this bio-pic. However, if you are unfamiliar with his story, you might make it through the near three hour run time. I was of the later and found it to be a competent film. There are some gaps that I will need to look up. For example, it seemed like it is assumed that you know about Malcolm X and his involvement with Ali (I do not). There are definately slow points, and, thinking about it now, I don't actually remember how it ended. I was pretty checked out at that point, and slightly distracted. I didn't hate it, though I don't see myself watching it again.
