Which one is more frightening, metal illness or the unexplained?

Rating: 8/10 (29 August 2018)

This is the question you will ponder when this film ends. I can talk from experience that loss in the family will tear a family apart. My sister was an infant when she died and I was three. My mother was depressed 24/7 and the feeling of guilt still haunts me to this day. There were parties and family photos looking happy, but underneath that façade, a dark memory lingers. I was never comfortable around my parents. I was always apologetic or trying to please them.
I find the first two acts did what it should. Set the mood right with visual cues that will be useful on the third act. There are some scenes that I find unsettling. The scene with Charlie and her brother driving to the ER for instance, did it happen or was he tripping? Cut to Annie crying hysterically. Masterful editing.
The third act is when events got odd. Was it some mental health they inherited or something more sinister. Surely a psychologist can help this family, but no. Nothing can help them or you because you are trapped with their horrific experience.
