Netflix crime documentaries are usually too long, and spread needlessly over multiple episodes. This feature-length doc is too short, and could have done with an extra couple of hours too tell more about the real parents, Michael's possible father, and the little brother "Philip" who was abducted with the three sisters at the beginning, and who (according to Wikipedia) showed up in 2019.
A very good documentary, nonetheless, and one that I will remember for a long time.
