The Rocky and Adrian apartment scene+relationship was nonsense
I've personally experienced a similar thing to how Rocky behaved towards Adrian in his apartment twice from my drunk sister. Even at the time, I doubt any person in Adrian's position and vulnerability as we saw would ever put up with that crap. But instead she eventually fully reciprocates his advances and they "officially" become a couple.
Also the love story itself came off as pretentious. There really wasn't that much time or impact with it, and the otherwise amazing and inspiring ending was slightly tainted by how she yelled that she loved him in the final shots, just like in a fairy tale.
