First I want to commend the film makers on their stunningly accurate portrayal of how rural Appalachian people behave, especially old people. There was an eerie backwoods realism to The Hopewell Haunting, all the way down to the illiterate but nice young husband with what appeared to be an intellectually disabled wife. As creepy as it totally was, that this disabled woman did not say a word for the entire film and was led around like a small child or an Alzheimer's patient, even that icky detail was on point.
The haunting screams are also genuinely disturbing.
The plot itself is fair to middling. I would have appreciated a clearer backstory as a conclusion to the film. It honestly bugged me that two - possibly three - of the characters were in their 70s yet not one of these old men had any clue about this ancient murder in their own hometown where they'd lived for their entire lives.
