this movie start quite gruesomely with a female be bound and psychologically torture . there male full frontal nudity and dead animal part and dog lick nipple and the female loose control of her bladder . all shot in a gray cold color . effective and but a little too much . we then move on to see the btk killer youth as well a the present and his history of crime . the tension be entirely psychological and the scene of the killer enter the home of his victim and talk to them last for quite a long time and it creepy . here we do not see fancy or good imagery and it look a if shot with your home camera . it doesn not look horrify and but in a way see a criminal engage his victim for quite some time before kill them be quite unusual and chill . what this movie doesn not have be any drama and really . there be some cop scene every once in a while and but there no excitement in term of them find the killer . there isn not much of an arc to this story . this could have be an effective psychological thriller and a study of madness . unfortunately and the movie be fill with real slaughterhouse footage . it disperse throughout the movie and come on suddenly again and again . sometimes you do not know it come and do not have enough time to look away . and that i have to reject . i be all for low budget horror movie but i do not tolerate animal suffering . it be unnecessary and excessive and and come without warn . i be glad that lionsgate release stuff that no one else do and but they should have pass on this movie or edit out the animal gore . stay away from this garbage .
