Provides Examples Of:
Color Wash: The scenes outside blow out the color, giving an orange wash.
Cruel Twist Ending / Gratuitous Rape / No Ending: One of the most egregious and notorious cases in recent memory. At the end of the film, the caveman (Petr) brutally kills one of the remaining survivors and rapes the other, and the film just ends right there.
Epileptic Flashing Lights: Basically the only source of light are the characters' flashlights. And they flicker to the point of inducing seizures.
