I found this very interesting and well done. It kept me watching non-stop till the end. Although I was familiar with the story, there was a lot more to it then I could ever imagine. They did a great job backing up their story with facts, actual witnesses, and law enforcement interviews. My only criticism is that it could have been a bit shorter. It did tend to drag towards the end. It probably could have been done in 3 episodes (or maybe 2). Either way - it did keep me gripped to the screen.

Yes the story is interesting and yes four (one hour long) episodes isn't a lot but they could have done the whole story in two.I felt like I watched the same scenes numerous times, the same info was given repeatly making me feel I had already watched this episode. Honestly if your going to watch it; watch episode 1 & 4 and the story will be told the exact same. Bit of a waste of time.Also Majorie is a loud & annoying which is no fault of the documentary but I don't need to see the same scenes of her screaming a tangent repeatly throughout multiple episodes.Far too dragged on to spill the beans in the last ten minutes of episode 4...

The thing is true yet is filled with twists, the ending is surprising, and it's never slow or dull. I don't understand how anyone can rate this thing below 9. In my opinion, a lot of Netflix content is subpar, but this is outstanding.

It's an ordinary and simple plot yet shocking from the very beginning. Story tells how ordinary grown up men can lose their rational and turn into pure evil.
