This one actually felt very exploitative to me. If you're looking for something to put the events of this case in a timeline - I guess, this documentary does a decent job. But that's all it does. It takes existing footage and arranges it in a specific order. It doesn't attempt to explore the reasoning. It doesn't attempt to uncover something you can't already learn from a simple Google search. It doesn't give it any kind of perspective. All it does is puts the a timeline together, puts the word "murder" in the title, and waits for the true crime crowd to tune in as it puts a family tragedy out on display.
