Reception
In a retrospective review, Christopher Forsley of PopMatters described "the entirefilm is unfocused". Forsley delved into the portrayal of femalecharacters, noting that "every female character no matter her age, faces a sustained threat of sexual assault." Despite the disturbing nature of this themes, Forsley remarked that "it's through this unrelenting threat that Bergonzelli's uniquely perverted voice is heard and the film is almost redeemed for its many failures."
