Late '90s/early-mid 2000s horror
Ok, I realize there are probably a hundred movies with a similar plot to these, and it's been over a decade since I would have seen this so a lot of this info might be straight up incorrect, but here goes:
An older teen boy and his family (parents, maybe younger brother) move into a rural-ish house in a small town, and something's going on in the backyard or woods behind the backyard, a burial site maybe? The dog might be attacked or something, and strange people are seen back there, there's probably a weird neighbor at one point. The boy strikes up a friendship/romance with an older teen girl in the area, and they do some investigating together at the local library or some cliche and find some crazy information and have to rush back to the house to save the family. Maybe a ghost took over the dad at some point and he's about to kill the mom and boy? Maybe I made that part up. Maybe I made all of this up!! Help!
(This was probably not a movie that was in theaters btw, and wouldn't have any huge names involved, at the time at least. Watched on FearNet or some other antiquated streaming format.)
