I don't know. If it is making entertainment out of people's pain then that's wrong.
However, if it is made well and shows people that these women were loved, were valuable, mattered, instead of being seen as 'just prostitutes', like somehow they didn't matter as much - because people (not all people, just 'people' ) think like that, don't they? It's not as shocking / bad / dreadful if the victim is a prostitute?
Well it IS! And if this programme shows that these were just poor young lasses who got into bad situations, then good.
