So Creeds kid as a good job and boxes on the side for reasons... and wins. But he doesn't want to do underground boxing, he wasn't to make it big like his dad, because he's the bestest of the bestest. And there is a LITTLE struggle here, a little of the heros journey, but Creed starts out on the top and sort of finishes there too... so he doesn't really grow or change as a character... ... because modern movies can't have that for reasons.
