Critix also corrected you about the 'Southern accent'

.
But how does working class fit into 'rags to riches' for you? 'Working class' does not necessarily equal 'poor'. You keep trying to fault this film for portraying a struggle from poverty to Lydia's current position, but that is not the point of those scenes. The very point is that Lydia Tįr is an act to hide her less than exalted beginnings, but nowhere does the film imply that it was a struggle for her to get to her current position. In fact, it was her exceptional talent that got her there.
You're simply ascribing a narrative to the film that isn't there, and the only thing you base this on is a (misplaced) accent.
