I get what you are saying, at any rate I am a true blue fan of Brooke shields.
She is proud of this movie, and what she did.
There were other things going on in The Blue Lagoon -- the movie explored ideas about civilization and societal norms, about innocence and survival.
In both cases, use the techniques of natural rejuvenation.
In one scene, she practices her banter with one of the regulars in the joint and he plays along, but when Livingston suggests that he go upstairs with her, he is outraged and insists he was just kidding around.
Brooke Shields was just 14 years old when she filmed The Blue Lagoon, the infamously sexy and slightly salacious island-set romance that capitalized on burgeoning hormones in a big way.
