Stupidity: Cole fell into the lake, and he said he couldn't swim. Instead of making any move to avoid being mangled by the boat motor Becky was aiming toward him, he just stayed in the same spot and was killed. Even if one cannot swim, it would be possible to hold one's breath under water for a while to escape the motor's range. It also seemed like he was close enough to the dock to simply lunge forward and grab onto it to stay afloat. Cole was close to the lake's edge - the water shouldn't be deep.

Stupidity: Becky possessed the mysterious key that the four neo-Nazi prison escapees were at the lake house to retrieve. Becky didn't know what the key was for, so did not have a vested interest in it. By first denying that she knew where the key was and later refusing to give it to Dominick, her father was killed. Had Becky simply handed over the key when Dominick asked for it, it is possible no-one would have been hurt/ killed. Becky keeping the key with no importance to her served to further the plot.

Factual error: Apex, played by Robert Maillet (a retired professional wrestler 6'11" and 350 pounds), forcefully slams Becky (played by 5' tall fifteen-year-old Lulu Wilson who probably weighs under 100 pounds) horizontally with her back hitting the ground from waist-high yet Becky is able to get up with no incapacitating injury that would be expected. Becky also manages to brutally kill him (as well as the three other neo-Nazis).

Continuity mistake: Dominick's tattoo on the back of his head changes from the time he was in the prison courtyard to when he was boarding the bus. The older tattoos underneath were not entirely covered up or removed, blurring the swastika that he had thereafter. The transitions that occurred didn't seem possible - a swastika on top of a circle would not turn into a clear swastika. In ONE shot of the back of his head, the entire tattoo was located higher than his ears while others went lower on his head.

Trivia: Becky is wearing black boots, which might be Doc Martens. If so, the yellow shoestring might symbolize that Becky is anti-racist. Or, it might not have any meaning or significance.

Continuity mistake: A vast majority of the movie occurs over the course of a single day, so it would be expected that Becky's hair stayed about the same. However, there were frequent fluctuations in Becky's hair's length, how her bangs were arranged, and color (whether the blue streaks could be seen at all or how much at a given time, and if she had dark roots on the top of her head).
