It has been a minute since I watched it.
I understand the cheating to get her son in, there is no way you would have your entire family leave your youngest child behind to die if you had that opportunity.
I forget the reasons that she was so mad at her husband, however as I recall he went to serve, and as someone who has deployed, her anger really didn't sit well with me.
The other thing about the series is just how damn lucky the "doctor" gets over and over. Yes, she is a smooth talker, but I felt that things always went JUST the way they needed for her.
Overall I found the series to be entertaining, and I will continue to watch it as new episodes come out.
