Corrected entry: Andy has the Chucky doll for a few days before his mother asks the peddler where he got it. When Andy's mother spoke to the cop about the doll working without batteries she said "it's been speaking and moving without batteries for days". When she asks the peddler where he got the doll she says "I bought a doll from you yesterday". How could she have bought it from him yesterday when Andy has had the doll for at least two days by this point?
Corrected entry: In one of the last scenes Andy, his mom, and the detective guy are sitting in Andy's moms room and a man comes in. The detective tells him about Chuckie and he doesn't believe him.The detective says " look for yourself, he is scattered all over the hall". How would he know that Andy's mom shot his body parts all over the hall if he was sitting in the room the whole time.
Corrected entry: After Karen comes home following Maggie's death, she first meets the detective who first assures her Andy was not a suspect (by saying none of his shoes match and why would Andy be on the counter?) Suddenly the detective fully points the guilt towards Andy saying "If Andy didn't make the footprints then WHO?" Basically, he contradicts himself.
Corrected entry: When Maggie falls out of the kitchen window, first of all, she supposedly falls because she stumbles backwards, startled or hurt from the hammer wound on her head. But there's no way she could stumble backward and gain enough force to hurtle through the window the way she does - it would be hard to throw yourself out the window and gain as much force as Maggie did. Also, she falls out the window backwards, meaning face up as she falls. Yet when they cut to an outside shot, somehow she's miraculously reversed to face down. A miracle in physics.
Corrected entry: It's in one of the first scenes. The little boy is making breakfast for his mother. He clearly pours a glass of orange juice and puts it on the tray. However once he gets inside his mother's room the glass now has milk in it.
