Do you know of any seriously scary horror films that the plot includes a killer?
Try the old version of “The Hitcher” with Rutger Hauer (I think that’s how you spell his name). I’m not a scary movie fan and I hated the movie when I first watched it. About three days later, while thinking about it, I changed my mind and decided that this movie is a classic. I don’t want to tell you why because that would spoil it. I have watched this movie several times since. Have fun.
