This is essentially...

... (if that can even considered be that) an unwittingly unintentional remake of the Swedish/Finnish movie "Men Can't Be Raped" (1978) (by the way, I have seen it yes, and WHAT a CONTROVERSIAL title) moved to Hollywood almost 30 years later, and is done in a sense that, unlike a vengeful act of brutality followed by murder like we've seen in the likes of "I Spit on Your Grave" (1978) and others, it has a female rape victim getting her revenge, but unlike that little seen classic, its almost as if if BOTH versions, a woman in vengeance raping her assailant with an object AND having a male perpetrator do such a deed instead of castration etc, were taken into account, which shows indeed that men can be victims of it too. Even if in both films it happens to such men that were PERPETRATORS of such act IN the first place.
