Copied "last house on the left "spoilers

This movie totally copied last house on the left right down to the disgusting savages going to the parents house , but without the redeaming revenge that last house on the left had where the parents get back at the killers and torture them! This movie was pretty well acted and the nipple scene was horrendeous . The director seemed to want to use shock value to gain attention for the film. I would have given it a higher rating if at the end there was a revenge on these scum bags !!
