Corrected entry: At the close of the film, the David and his friends cannot break through the windows of the house because they are a special reinforced type. However upstairs, when one of the bad guys is trying to get into a bedroom window, Nicole takes an umbrella and easilly shoves it through a regular window, breaking it, and injuring the bad guy. Clearly Steve would have had reinforced windows throughout the entire house, wouldn't he?
Corrected entry: When David hits Nicole by accident he hits her across the right eye. Then the next day the bruise is on her left.
Corrected entry: In the car chase between David and Margo, there is an oncoming car which forces David's car off the road. If Margo is terrified of David, why too does she pull over and stop? The oncoming car was not in her lane and she did not have to avoid it in any way.
Corrected entry: When the girl and her brother are playing the games console and her friend walks in. She leaves her brother but it was a two player game and both sides are still fighting, instead of one.
