Don't watch this unless you enjoy constant disappointment. Nothing is ever solved. When it is, it's some stupid explanation like "She's not possessed, it's the lights." It keeps you hooked with glimpses of the devil or demons and constant promises of supernatural action but it's less exciting than an old Goosebumps book. Actually, the new Goosebumps show is more well written than this mess.
Kristen is a horrible person the entire show. She's allowed to kill people and cheat on her husband but she's a good person and faces no consequences for any of it but it's everyone else who's evil. It's like it was written by a teenager.
Don't get me started on how the writers clearly have no idea how children actually act since in the show, they're written as a cackling monolith that moves as a unit and they are almost never seen alone.
