Rotten Tomatoes and Audience scores
There was a Rocky marathon of most of the movie in recently and I thought the ratings on these were interesting. These were the order that the movies were rated from best to worst:
Rotten Tomatoes - Creed, Rocky I, Creed 2, Rocky Balboa, Rocky 2, Rocky 3, Rocky 4, Rocky 5
Audience - Creed, Rocky 2, Creed 2, Rocky 4, Rocky Balboa, Rocky 3, Rocky, Rocky 5.
