It took me about 45 minutes into the movie before I realized that this movie was very loosely based on the life of Theresa Knorr and the horrors she inflicted upon her children. I read the true crime book "Whatever mother says" a few years ago and that was hands down the most awful real life story I have ever read in my life. This movie does not even begin to come close to the book. After watching this horrible effort of a movie, I realized that the unspeakable acts of Theresa Knorr cannot be turned into a good movie. If you want the know the real story, you should read the book. It is completely different, apart from a few of the horrors shown in the movie, but the book is actually a hundred times worse and more painful. Read it to educate yourself in the world of true crime, but be prepared for a disgusting ride into reality.
