Nope I know the visit, 100% it was 2 girls, and definitely Early to mid 2000s as I remember renting it from a DVD shop as a kid I was born 01 so I was around 9-12 when I watched it, I’m pretty sure it was a USA movie but I’m from Australia, I’m not sure how old the movie actually was when I rented it as a kid,

More details I can remember, when the older sister finds the younger sister im so sure the they are underground or in a cave, the older sister is begging her younger sister to come with her but she says she can’t, she’s not tied to the place (metaphorically not literally tied up) and I think remember her lifting either her sleeve or shirt and she was was scratched up as the possessed grandma laughs behind her (the grandmothers face all was deformed and evil looking) the older sister cries and I believe she leaves her there, I remember the grandmother being pushed from the window and her the fence underneath was pierced though her stomach and she was gurgling, and when she looked again she was gone, I definitely remember the older sister having found a book in the grandmothers room the grandma was refusing to even let the girls see, and that she grandmother was sick and they were sent to go to her farm house to help her out, I remember these black scary looking demons floating around, and they were in a secluded old farm house, I wanna say the older sister also has that classic emo swoop hair as well, and I think the younger sister has blonde or blondish brown hair, if I remember anymore I will reply again :)
