Don’t Hang Up (2017) 3.5 out of 8 horns barely up. A couple of teens make prank phone calls until they get pranked themselves. These kids are dicks and we were rooting against them! VioletHör gives it 1.5 out of 4, mediocre acting, standard plot. Kevin131 gives it a medium 2 out of 4, this movie is trying to be Scream meets Saw or something.
