Honestly i feel soo empty but satisfied

I just finished watching this movie and i can feel what the guy is feeling at the end of it when he walks away .great acting from the villian.one scene that truly gave me chills when he knocked on her car window ,she said she was alright and was just going to wait for the towcar and he just stood there staring at her then smiled .haaaaa it had me chills .
I feel like the devil in this story was not the villian but the victims boyfriend .he was dealing out repeated punishment like how hell is mostly depicted .a never ending torture scene .

i was thinking twice before watching this,but i have to say its really good the casting was perfect ,am so inlove with the soundtrack it fit every scene perfectly would ask for more ,maybe there were a few things they might have changed in regards the characters reactions overall am happy
