Classic narcissism
This movie was disgusting. I had to stop it before the end as it was a thinly veiled narcissistic fantasy.
What do I mean by that? The narrator is completely self-centered (and I presume using the author's words from this supposedly true story). As people have pointed out, she was a bitch to the new cook. Ok, she was 10, right? She only warms to him when he gives her great food and books (i.e. he is a provider). But consider these other points...
She is upset that she doesn't get her first kiss at the prom. There is no attempt to understand his feelings about it.
There is no interest in the guy on the bus but when he puts his own life (and those of others) at risk to rush her to the hospital to save her baby. He then earns value as a protector. But then, at his wedding, we learn that she actually did him a favor and turned his life around (so presumably she doesn't owe him anything for saving her and her baby).
Of course, he cannot be the love interest because he is a drunk and killer. No, the love interest should be...an old high school friend who is now a handsome doctor and is completely smitten by the single mother who works in a diner and didn't finish college!!!! And of course, your best friend from school is filthy rich (but unhappy).
All of the men (and most of the women) are judged by what they do for her, not as independent adults with their own needs and desires. Her own mistakes are trivialized (I got pregnant because I wasn't over my mother's death) but I'm happy to let Mr Church support us.
On the latter point, the movie first suggests that the mother's lover (conveniently a married millionaire who is willing to provide for his mistress after his passing) paid for Mr Church's services. The daughter can't be his because then they would have to explain why she didn't get an inheritance.
Later, she said that the money was only for six months and that Mr Church supported them from his own resources for years. How you might ask? Playing piano in a jazz bar at night? Other have suggested that he may have been gay and therefore he represents no sexual threat to the main character. It really doesn't matter, he is just a tool. She shows pretty much a complete lack of empathy on several occasions (including ignoring his multiple requests to leave his personal life alone). This is another huge narcissistic red flag. I switched it off when she started supporting him (again without any visible source of income).
This is nothing but a Cinderella story updated for modern times but with Cinderella bringing nothing to the table other than to have people look after her and make her the center of attention.
The sad part is that narcissism scores have been increasing over time so many people will see nothing wrong with her entitled behavior.
