Casey locks a door twice
When she's talking to the killer, she locks the same door in her house twice.
Where was Steve's killer?
When Casey got her question wrong, the killer killed Steve. The only problem was, the killer wasn't there when Casey turned on the light. The killer didn't have enough time to get away so she should have been able to see the killer.
Casey can be heard screaming
When Casey is running away from the killer, the killer puts a hand on her mouth. You can still hear her screaming even though her mouth is covered.
Casey had blood on her back
The killer stabbed Casey in the front (chest or shoulder area), but when she tried to call out to her mother, she had blood on the back of her sweater.
Sydney's father knocked
When Billy snuck in Sydney's room, he made a lot of noise. Her father clearly knocked on the door which was why she wanted Billy to leave, yet when she opened the door, she asked him “Can you knock?”
Reporters at school
Why were the reporters at the school when Casey and Steve were killed at Casey's house? Why did they assume that their murders were related to someone at the school. Their deaths could have been random killings.
When Sydney fought the killer
When the killer revealed himself/herself in her house, they got into a fight. You could clearly tell that Sydney was a stunt double.
Why did the killer let Sydney sleep?
Sydney fell asleep while she was waiting for her friend Tatum to pick her up at her house. Sydney walked around her house and there was no sign of life in the house. However, when the killer called her, he/she jumped out at her from the closet. My problem with this is that if he/she were already in the house, why didn't the killer get her while she was asleep?
Gale was always around
How did Gale always know to be around whenever something happened? Unless she got tipped off by the killer/killers, she shouldn't have known to be around whenever something happened.
The killer changed outfits
When Sydney was in the bathroom, the killer was in there. There was a camera shot of the killer's pants, but they weren't the same color as the paints the killer wore earlier. It was still the same day so when did the killer change?
The killer wasn't spotted
The killer was outside in broad daylight dressed in the costume, but no one saw him/her.
Stores closed for curfew
The police issued a nine o'clock curfew for the town, but the people were closing up the stores before sunset.
Dewey allowed the kids to drink
When Dewey went to the party, he saw a teenager with a beer. He jokingly told him that he was under age. Why would a cop allow teenagers to drink?
Tatum went out the cat door
When Tatum tried to escape from the killer through the cat door, a stunt double was used. Tatum's hair kept changing so you could tell it wasn't the same actress.
The batteries fell out
Just before Randy goes over the movie rules, he pauses the tape. When he picks up the remote to pause the tape, you can see red batteries fall out of the remote.
Sydney stayed on the property
The killer wasn't after her anymore while she was at Stu's house, yet she chose to stay there instead of running away from the house.
SPOILER WARNING
Sydney should have known that Randy wasn't the killer
When She's in the news van with Kenny, they see a footage of what's going on in Stu's house. Gale put a camera in the house so she and Kenny could see what was going on. Sydney saw how the killer was going after Randy so she should have known that he was innocent.
Randy's limp
Gale hit Randy on the head with her phone when he walked up to her news van. For some reason, he ended up limping when he wasn't hit in the leg.
SPOILER WARNING
Why did the killers keep stabbing each other?
When they were talking to Sydney about their plan to set up her father, they stabbed each other. How did they expect to kill Sydney and her father if they were wounded from all of the stabbing?
