Sylvester Stallone wrote the script for Rocky, then famously used the script as leverage to star in the movie as well. It's one of the films created by a member of the Boom generation that was seen as the start of a new generation of filmmakers. It's also the first of them that has a story that works with the associated Prophet archetype.
If you haven't been here before, please take a look at the Introduction to Generations, the Generational Attributes and the Four Stories in order to get up to speed on how all this works, and the terms being used.
“Rocky” appears at first to straddle the line between the Doomed/Damned Artist movies of the New Hollywood period and the Good Guy Wins paradigm when Boomers started taking over. After all, Rocky doesn’t really win, does he? It’s a split decision, leaving Apollo Creed as the undisputed heavyweight champion. There was even an original ending, as seen on the poster, of Rocky and Adrian walking quietly away from the fight, humble but happy. It’s not the absolute victory seen in Jaws and Star Wars nor in the dozens of sports underdogs movies that followed over the next 20 years.
Still, by the given criteria, it’s rather clear that Rocky belongs with the Boomer movies rather than Silent Generation (Artist) ones. First: Are the protagonist and the other main characters either Doomed or Damned? If not, is there a good guy and a bad guy with the good guy winning? For Rocky, it’s much more the latter than the former. While Creed wins the bout - except that, really, he doesn’t lose - Rocky succeeds at his goal, to go the distance. He even surpasses it, by managing a split decision against the World Heavyweight Champion himself. Creed’s victory doesn’t neutralize Rocky’s, doesn’t make anyone’s life worse, doesn’t mean Rocky gets his fingers broken. (If it was a real New Hollywood picture, that twist could easily have found its way in: Rocky’s big break gets the unwelcome attention of his bosses, and he has to lose in order to stay alive, or completely annihilate Creed in order to “win.”)
There is - like Jaws and Star Wars, unlike The Godfather or Network - a definite Win for the protagonist that doesn’t lead to death or damnation. Still, Rocky doesn’t manage to be as audience-friendly as those which came after. It’s a long, slow drama that builds to an intense but not lengthy (under ten minutes!) fight sequence, which fight is the only real “action” in the whole film. (If you think the “Gonna Fly Now” montage is an action sequence...he slurps eggs, runs, gets to the top of the stairs, and raises his hands over his head. Stirring, excellent, not action.) Rocky gets to know the “pet shop dame,” argues with Micky and his boss, negotiates with Creed’s manager - almost all of the film is him talking with other people, and not always in a way that puts him in the best light. While it resembles New Hollywood's Artist movies in this way, it clearly is, and was, another stepping stone to Blockbuster Hollywood.
