I found it very emotional , based on a true story, up until she leaves America.
My cousins wife did the same thing, from the same community, but to Britain, her and her sister. My parents took them in and that's how they met my cousin, this was 25 years ago. We are all very close and things she told me were mirrored in the series. They also had people coming over trying to take them back. Her sister sadly committed suicide which I believe was due to her having her children taken away , at the time there was 3 under 2, all babies and she was only 19.
Also, if you do watch, make sure you watch the making of' it's just very interesting.
