Movie submitted by Frankie:
So, I have no IDEA what the name of the movie was I saw it a few years ago.
(that I remember)
It starts off after the events and kids are going into the open door of the house, then it flashes back to the night before and they have just gotten married and are staying in a friends house or something, weird things start happening(I dont remember a lot of the middle) the guy walks outside and sees a guy in an animal mask. Eventually the guys in animal masks come inside with baseball bats and kill the husband and they think they kill the girl, but the kids walk up to her and she is still alive, barely.
I thought the name was something like “The Neighbors” but I have been searching for hours.
