As the mother of a little girl I had such a hard time watching this story. It is completely captivating and Cathy is an incredible woman. It's rare that a true crime documentary grabs me in this way without leaving me sad and stressed. The way the story unfolded and the reveals felt natural and welcome, not overblown or manufactured. The story is just actually that shocking.
So many themes are present that are timely in today's world - the myth that all adoption stories are full of hope and positivity; the way women in abusive marriages are brainwashed to ignore, deny and defend the abuser's behaviour; how the policing and justice system fails missing, abused and murdered women every single day.
The 'reenactment' B-roll scenes were cheesy and unnecessary, and the format would have been better split into 4 shorter episodes, as the two halves both felt like they had natural split points. Otherwise, very successful. Highly recommend.
