I like the subject of the documentary series. It's a fascinating premise and the reveal is ALWAYS interesting even if repetitive.
This being said, there is so much "producing" happening off-camera (or scenes that end up on the cutting-room floor) that it can come off as unbelievable (staged or fake). As an example, the episode where the online guy who was supposed to be a model turned out to be a younger female. She lived in a separated garage-turned-bedroom in the back of the household that they drove to. When they arrived onto the premises, it was all too easy to find their way to the back of the house, then suddenly hear some noise, then the person willfully comes out to meet them when she could of stayed hidden? It's too far-fetched the way that this reveal happened.
I wouldn't be the least surprised if a producer went ahead to the residences and met with the online people first, off-camera, to get their story. Then on the day when they schedule the visit, a producer is with them inside already to make sure the encounter happens. If this is how they do it, I understand why it may be necessary, but it does add a sense of unrealness to the already odd and uncomfortable situation.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
