Factual error: When Grace goes into the children's bedroom to wake them up to introduce them to the new nanny and maid, she takes the only lamp they had with her into the bedroom but light is still reflecting off the nanny and maid as if a lamp was still there. (00:08:20)
Factual error: As Anne is standing in a room at the beginning of her punishment, the camera pans sideways from her past a piece of furniture with a small statue on the top of it. From behind the statue comes a light whose color and quality could only be electric in origin. It is a greenish fan of light, like one of the old "TV back-lights". (00:27:45)
Answer: Evil and good do not come into it at all. They are simply dead people. As Mrs. Mills says it, sometimes the world of the living gets mixed up with the world of the dead. They simply died in that house and can't leave just like Grace and her children.
