I saw it and was very intrigued by it. At first the sister and daughter protrayed a very loving sister and mother. After meeting the pathological liar brother, learning about the psychological profile of Patricia, and hearing her interview - clearly that family is very, very dysfunctional. As the show went on, the sister seemed a little off too. I genuinely feel for the daughter though. I think the liver cancer story was made up after she was arrested. Clearly it wasn't mentioned in the autopsy and over 10 years after his death, I'm sure there were no medical records and she seemed to easily influence her family. Definitely a weird case.
