i think it was an epidode of a show, but there was this girl who was really bratty, and she got a doll that looked like a tiny her. the doll replaces her, or something similar and blames her for lots of bad things.

the movie starts with a man changing a days without accidents sign to 1 and toward the end there is a monster who wants all metal things and this main character kid has to give up his dead moms locket to save this one girl who is the daughter of the man the dead worker died for beause she took his shift because he was drunk.
