If someone describes it as a black shadow, IT'S A BLACK SHADOW
Way too much artistic license taken with this show in season 3 and 4, it's completely over the top, am I supposed to believe that every haunting in America now is a reiteration of Jeepers Creepers? Give me a break. And there are too many jump scares. Less is more when it comes to these. I thought we all knew that by now.
Season 1 and 2 at least had SOME plausibility. A haunting is supposed to have some mystery to it. We don't know how this phenomenon happens if it really happens at all, so I think it would be common sense to keep some sort of subtlety. If a witness describes seeing a black shadow, it's a black shadow. An unexplained errant shadow is scary by itself. I don't need the goofy demonic facial prosthetic and jump scare.
