Corrected entry: When the Ragdoll grabs onto Lucy's shirt, you can see it's hands have been sewn to the shirt, it seems this was done to make it look like it's gripping and pulling it.
Corrected entry: In the beginning of the movie the ghost of John Barlett is haunting the Bradley house, and attempting to kill Patricia. If he and Patricia have been reunited all along, why would he attempt to kill her?
Corrected entry: When Frank goes into the freezer he is wearing shoes. Then when he's a ghost he is barefoot for whatever reason. Then he goes to heaven and he has shoes. Then he goes back to his body and he's barefoot again.
Corrected entry: How can Ray (when he is a ghost) be stuck in his own grave covered in dirt if he can go through matter?
Corrected entry: When Dr. Lucy Lynsky is first being "spooked" by Bannisters ghostly friends, she is on the bed when it floats into the air. You can clearly see the big lifting mechanism under the bed in the first shot. After it cuts away and cuts back, they finally remembered to remove it from shot in post production.
Corrected entry: When Lucy is trying to get Patricia out of the house because they know Johnny is back and killing again they make a mistake on the number of people killed. Patricia is talking with Johnny although Lucy doesn't know it. They are waiting downstairs for Patricia's mother. We don't know yet but Patricia killed her mother upstairs. Johnny and Patricia are saying they should kill Lucy and make her 41 on their kill list. However, her killing her mother upstairs should be 41. In being so careful on counting how many people they killed all movie long they completely forget to count that Patricia killed her mom. She should be the 41st death and have that carved in her head.
