It seems rather strange that a historian, not a lawyer, would be contacting someone to tell them to take things from a house. Either she has inherited the entire property, or none of it. If she has a claim to the house, that would be the news to tell her. If not, he's essentially encouraging her to break-and-enter and steal.
The Foley for the clicking heels in the beginning is wrong. Specifically, there is an echo (the Foley was recorded inside) even though the actor is walking outside. It also appears, in the close-up of the shoes walking in the very next scene, that the clunky wooden shoes actually have a thin rubber layer on the bottom, so wouldn't make clicking sounds anyways.
As a general rule, women do not stand in front of a mirror seductively unbuttoning their nightgown and fondling their own breasts. At least, this is not a reaction most women have to sleeping in a strange place after creepily being stranded by car trouble. Male filmmakers make women do these ridiculous things just to titillate their young male target audience.
Even frightened women would not run barefoot in a derelict house, they would put shoes on as they got out of bed.
Before Kris' friends arrive, when the camera zooms into her face in the hallway, you can see the tracks on which the camera moves along on the lower part of the screen.
An ancestor who lived over three hundred years earlier would be much more than a "great-grandmother" and no historian would make such a mistake. It would be more like a great-great-great-great-great-great-great-great-great-great-grandmother.
The warlock is shown "sharpening" his blade around the 38 minute mark, but he is doing it all wrong. Especially with a rough stone (not the smooth, commercial ones available now), it's even more important to hone only the edge of the blade lengthwise. He's just scratching the blade by moving it slowly, not in a straight line, and across the width of the blade. (Also, the Foley sounds like he is actually sharpening the blade correctly.)
