Victoria Principal has said that she feels Pam changed throughout the course of the series. She commented, "Pam didn’t have two parents, her father was a drunkard, and she really had to fight for everything she aspired to and achieved. When Bobby married her, he wasn’t marrying a milquetoast; she was very, very spirited; she was always a good person. I always felt Pam was the moral centre of the programme but she was complicated, and she was fiery, she had opinions, and she was not afraid to voice them. But as the years went by, as J.R. became more and more evil, the writers felt, and I certainly understand why for the benefit of the show, that Pam had to become more and more good." When asked about whether she had any input on her characters growth, she said: "Once the show achieved extraordinary world wide fame, I don’t think any of us had much input. You know the old saying, if it's not broken, don’t fix it; I really believe that Lorimar Television looked upon it as something that was working and they did not want to deviate from the formula."
