Continuity: When Tosh is on the computer she is in a Gothic chat room. As she types her first message you can see it is for the entire room. But as the shot changes it is now for just one user. It happens too fast for it to be a technological intervention.

Plot hole: In one gruesome scene, the killer hangs Natalie's friend in the woods and then crashes a car into a tree. Natalie escapes and comes back with campus security (who didn't bother to call the police even though a murder had just been committed). When Natalie and the guard get to the murder scene, all evidence is gone. How did the killer manage to remove the body and all pieces of the car within ten minutes (not to mention somehow hide the dent left in the tree by the car crash)?

Continuity: Near the end of the movie Natalie finds Brenda laying on the bed. Then suddenly Brenda gets up and suprises Natalie by punching her on her right [our left] cheek. However when Natalie awakens, tied to the bed, the bruise is on her other cheek.

Continuity: When Natalie is in the car, all of a sudden the tapping on the car roof starts, like the Urban Legend. The thuds and taps cause the passenger seat sun-visor to fall down. But in the next shot from outside, it is pushed back up.

Continuity: When Brenda is caught wounding Natalie by Reese, she backs away. As Reese points her gun at Brenda and tells her to back up, between shots Brenda's coat keeps changing it's position on her shoulders from on or off them.

Continuity: When Sasha is pushed over the banister by the killer, she grabs the corner of the stairs; as she hangs on, her hands change position. In one shot she has one hand either side of the corner. Then she has both hands on the right side, then back again.

Continuity: When Natalie and Paul are talking upstairs at the party, at one point Paul puts his hand up by Natalie's ear. Natalie then puts her hand up on Paul's wrist. However between shots the hand she placed on his wrist keeps appearing then disappearing.

Audio problem: When Natalie shoots Brenda backwards, causing her to fly out of the window, we hear the sound of smashing glass as she flies out. However there was no glass; the window was missing and the hole was boarded up with planks, so we should not hear glass.

Continuity: When Natalie and Brenda are walking across campus and come across the stall with Paul's newspapers, Natalie picks up one of them. Between shots, the way she holds it open changes from holding it in the middle, to the top.

Continuity: In the opening scene with Michelle driving, there is a wide shot of the dash board, and you can see the pointer is on fifty-eight mph. Then in the next close up of the low fuel signal, the pointer is no longer there.

Continuity: When Natalie is in the car, she is unaware that tied to the back is rope which is also hanging Damon from the tree. When she reverses, this causes him to crash into the windshield. However between shots the way he is falling and the way he lands is inconsistent.

Continuity: Inside the radio station tower, Sasha is just being introduced to a new speaker calling in. The equipment assistant holds up a card saying 'Felicia' for Sasha, with his left hand. In the next shot it is in his right.

Plot hole: When Natalie and Damon are in the woods when Damon goes to the bathroom and the killer approaches him from the behind, it cuts to the scene with Natalie in the car. Then she gets out and sees the killer then runs to the car. You see the killer put rope on the car but how does the killer hang Damon without Natalie noticing?

Factual error: If you cover someone's mouth with a 2-3 inch strip of duct tape, or electricians tape, rather than go around the entire head, it is VERY VERY easy to repeated open your mouth wide, then scrunch face over and over again and work the tape off to the point where you can scream. Actually, duct tape, which is used by most of the offending movies is even easier than that.  It can usually be almost completely removed in a matter of seconds.  Electricians tape as used in this movie, is a little harder since it is stickier, by still can be done fairly easily. I suppose that it can be argued that people in these situations are scared, or don't know any better and therefore don't TRY to remove it. But in this movie, the main character is getting her stomach cut open and screaming in intense pain.  This would cause enough facial movement for the tape to work itself free.

Continuity: Brenda is showing Natalie a slideshow using a projector to show her how her boyfriend was killed; she firstly shows a photo, then a newspaper article. The article is left projected for the whole scene. That is until Brenda is shot out of the window, and now it is the photo that is back to being projected.

Continuity: When Michelle gets back into her car after escaping the gas station attendant, as she drives following the moments up to when she is decapitated in her car, her wet fringe keeps on changing position between shots.

Plot hole: When the girl in the car gets killed she is decapitated with an axe. All you see is her noticing someone in the back of the car then a shot of an axe coming through the driver's seat window. How did the killer manage to swing an axe in a car and take off someone's head whilst he was sitting right behind her?

Plot hole: When Natalie and Brenda are looking at old Stanley Hall and hear moaning, they back away. The culprit, Damon, is suddenly behind them. As the noise was coming from just inside the building, how did Damon magically appear behind the girls in the space of seconds? No one is that fast.

Plot hole: Natalie and her friend once forced another driver off the road, resulting in an accident that killed the other driver. Natalie and the friend then admitted this to the police, and their punishment was... ONE YEAR'S PROBATION?.  Is the American justice system really this lenient?

Plot hole: How did Brenda get from the woods to her car and onto the road where Natalie was in the minute or so from the time she falls in the woods to the time she runs the janitor off the road?
