This is a very entertaining show and the 28 day theory is interesting. I'm on episode 3 and am planning to finish the first season. I don't really care that it's scripted, because I think the investigators needed guidance for good production. However, I do find it cringey at times, whether from bad lines or the investigators not being used to cameras/being filmed.
I do have doubts that this is real, considering just how much happened in the first night at every location. I've seen a lot of paranormal investigation shows, and not nearly that much happens in the first night, with rare acceptions.
