I liked the fim, but...
What about this:
Why Didn’t Ali Give George Foreman a Rematch?

George Foreman Believes He Was Drugged Just Before His Fight With Ali!

and,
1.) Sonny Liston's dive;
2.) George Foreman getting to his feet at the count of 8 but the ref. calling the fight;
3.) Ali's outrageous mouth (ex.: calling Liston an ugly bear, and Frazier a gorilla and an Uncle Tom); and,
4.) The two shady Leon Spinks fights.
You say Ali is the greatest? Maybe, but he's still a boxer and that sport is filled with fraud. Ali, it seems, is part of the fraud as well.
Consider this:
"There is also maybe five or six instances of fights being stopped by the referee when Ali's opponent takes two or three punches but still looks capable of continuing and is not in any serious danger. And again, there's a lot of times his opponents dramatically drop to the floor and roll around, or play dead while the ref counts to ten when there is no clear knockout punches thrown. In all of these fights the opponents seem to recover miraculously and have no problem congratulating Ali. 25 of Ali's KO wins have came as a result of the referee stopping the fight."
I do fault him for not giving Foreman a rematch, and it speaks volumes about Ali as a business man, which seems to be the polar opposite of his status as a great fighter.
