The Rocky movies are just relatable specially if you are a competitor. I rewatch all of them this year with my wife, and the only one that didn't touch me in the feels, or that I couldn't relate to was rocky IV.
With that said, I still almost rank them in order
1-1
2-2
3-3
4-5
5-4
6-6
The creed movies just missed something. The idea for the last creed was amazing, but poorly executed. Felt rushed, wasn't able to relate, should have developed more.
