The Skeleton Key 2: GET OUT
I saw the trailer and well... This is just like the Skeleton Key, which I liked.
Only thing is the possession thing came as a complete surprise at the end.
Yeah, I immediately thought it could be similar to a few, including the one you mentioned.
Mainly:
Skeleton Key
Wickerman
The Invitation
All great movies, all have different plot twists, but it gave me the same vibe.
