The film was panned by critics, who described it as one of the worst films of 2015. Critics noted that while it succeeded in being "100% politically incorrect," its main character, Warden Bill Boss, was so annoyingly loud and screechy that he made the film nearly unwatchable. The movie’s box office was a mere $18,976, a stark contrast to the original's modest success.
In the broader landscape of horror cinema, the film is frequently categorized alongside other "New Extreme" and transgressive works like Hostel , Saw , and A Serbian Film .

Instead, it relied on a singular, static, and unforgettable image of human degradation that permanently etched itself into the collective consciousness of modern pop culture.
