Continuity mistake: When Ashley is locked out of her house and decides to stay at Kale with Ronnie, she is wearing a brown skirt, up until a scene when she is at Kale's computer (still stranded/locked out) and she is wearing jeans. Where did she get these if she was locked out of her house? (00:35:30 - 00:39:05)
Plot hole: When Kale and Ashley escape from Turner, Kale tells Ashley to make sure the police come. But, when the cop comes, Ashley does not seem to have told him about what just happened, he gets killed before he can request backup, and then the police arrive right after Kale and his mother walk out the garage after defeating Turner. Why did she not inform the cop and wait all that time to call the police?
Continuity mistake: In the scene where Ronnie is breaking into Turners car, he has a spatula and some sort of long instrument that he has used to break into the car. They are lodged into the window frame of the door. Suddenly, Kale informs Ronnie that turner may be heading home and Ronnie starts to make his exit from the vehicle. The spatula and long instrument have now disappeared.
Plot hole: When Kale and Ashley are hiding in Kale's dad's office before Turner breaks through the door, the power goes out. Kale's ankle bracelet goes off when he and Ashley cross the line. However, considering that at the beginning of the film Viola Davis explains that the police will come immediately if the machine that traces the bracelet is unplugged, the bracelet should have started when the power went out.
