Adonis is really an...
Arrogant knobhead.
Apollo was also arrogant, but he really had class, while Adonis character is build up as a ghetto jackass that is really hard to cheer during this one. Young Drago had some real drama behind him, while Adonis looked on his period 90 % of the movie. Very unlikeable.
He got away with it in Creed, but in this one he is really annoying from minute one.
He really seems like he doesn't care about Rocky, his rant before the first fight with Drago and dropping the "I take care of you when you had cancer", that really was out of line.
And that cringy moment when he came in Moscow, with his wife singing. Jeez, that was really hard to swallow. And the n word moment.
He's no Balboa, that is for sure. Not a true champ.
