I expected a more win-win ending instead of a typical one.
Florian Munteanu (Drago's son) acted the best in my opinion showing perfect amount of emotions in between. You would feel more sorry for him than the joy for Creed's win (of course we would not want Creed to lose, still).
Creed (already the heavyweight champ) keeps his title, sure. But Drago's son looses a little that he had while being at no fault himself for Creed's father's death, seemed unfair to me.
