First of all, I don't think it's valid to use gender criticism to make personal assumptions about the writers. Gender issues in films tend to reflect cultural ideas rather than solely personal ones. Second, I think Ben and Henry minimize the Gypsy stereotyping here, which is as egregious as any racist portrayals in Hollywood history. The only ethnic groups that fare as badly are Italians (all of whom belong to the Mafia without exception) and Arabs (who are nearly always villainous and on the verge of blowing things up).
The protagonist's journey has less to do with the fact that she's a woman than it does with her occupation, although her gender does play somewhat into the politics at her job. Still, note that her success at her job has nothing to do with her looks or sexuality--she is the front runner for a promotion because she a) is good at what she does and b) she shows that she has what it takes to be a heartless capitalist banker.
The ending of the film seems to signify that self-knowledge of one's wrong-doing after the fact is not enough to save you from hell. One's choices lead to inevitable conclusions, and no half-hearted confession will wipe away wrong-doing.
