Biggest bullcrap going. In typical Baggins style, he narrates in a low monotone to create a sense of impending doom and despair.
You'll be fed the back story, people will be interviewed (witnesses and supposed 'credible' sources), then he takes you on a tour of the macabre, playing on the fears of the unknown & unexplained, to scare you.
EVERY place he investigates is 'evil & demonic', and true to form he gets 'taken over and affected' by some or other disturbing entity which results in: (1) making him angry; (2) lashing out at his crew; and (3) conveniently zoning out. Thereafter he has 'no recollection' of said events because he lost time or blacked out - followed by an overanalysis of events and a down-the-garden-path explanation. This is but a frequent occurence in his GA episodes.
I've seen my own weird otherworldly, unexplained phenomena. But even I can seriously rationalise that not everything is this world is satanic & demonic.
And trust me, they can tell you "oh we're making a doccie and we're not in it for the money or sensation, we just want to expose the truth". But at the end of the day, it's a production picked up by a streaming service, for mass distribution, ratings and money. Hype increases viewership, sales and revenue. And before long, they bring more of the same prescribed recycled ghost-hunting episodes (same M.O., different venue).
I'm not discounting that people can and do have genuine paranormal experiences, this world is just too vast to understand and explain everything. But you have to look at this stuff with a healthy amount of logic & reasoning.
Anyway, rant over. Watch if you want to. You won't get your time back.
