Solid Ending But...

Rare for a horror movie, I liked the closing scene. This wasnt bad but couldve been done much better overall. It got sloppy in parts. Like the burning of the son's stuff in the backyward in the trash bags - the dad doesnt even ask why all his son's stuff is in the bags upon seeing them for the first time? Then we have the tribe people on the property pointing at the house and again, the dad doesnt even ask why they're there?
