It's nice but i have a lot of question watching this movie... like why is Brahms like that? Did something happen when he was a child why did he went crazy or something? And why did the parents didn't do anything like put him in a mental hospital where he can get help? It's not supernatural anyway like anabelle why does the parents seems so scared like don't they talk or treat the real brahms like they do with the doll? Why would they kill themselves?
