I like to keep an open mind when reviewing movie. This one is garbage.
The acting is good, except maybe the mom's script, and the set up is good too. The ending is so dumb, and has no logic. The attackers way of moving around the house, and the owners way of losing track of where the daughter is makes no sense. The whereabouts of the bodies makes no sense.
The ending honestly feels like satire. It's like they had one director for the start, then ran out of funds and the director/scriptwriter left for the ending, and they left it to someone on crack to finish it off.
