The ‘Prostitute with a Heart of Gold’ theme is very old.
The heart of gold aspect is not objectionable.
The depiction of a life where the clients are good looking and ddon’t have the prostitute doing things that they dislike is unrealistic. The idea that some john would rescue a prostitute from the life is far and away an exception - they need to get out themselves.
There was no depiction of disease, or internal tearing, or rashes, or the long litany of health problems which go with commercial sex.
The movie glamorized prostitution and made it enticing.
No sale.
