ADVICE TO ALL: Watch this more than once after you have read several of these reviews and find that you want to watch this once.
I watched this a year ago and it was transfixing, totally fascinating, incredibly well edited, from both video, narrative, and sound/voice/music mixing.
There is nothing that could be a real life story that is more absorbing in these 2020's, when so many of us Americans have video cams on our phones and house exteriors and police everywhere else.
Now, a year later, I came across it on my list of liked Netflix videos. So I settled in and watched it once again. I'm more impressed the second time through.
Some haunting things I might have not paid attention-to the first time through: the airport arrival scenes with the two little girls, the wedding videos and speeches at the reception, the texting back and forth of husband and wife over the summer, the video of the polygraph and the professionalism of the police and all law enforcement. And of course, those fabulous friends and neighbors and their concern for Shannan and those children. And then, the brave mistress' honesty. She is brave to expose herself and help in the solution of this and the making of this documentary.
This is a fabulous documentary mystery crime story. The only problem with it? It's a story of real life and death.
