I love the Halloween series (Michael Meyers). I love watching scary movies. For some reason I don’t get scared I just find the storyline of interesting if it’s something like insidious or conjuring
A suggestion here, again from an older guy. You might if you haven't, want to get your hands on some of the 1930s/40s Universal Studio Horror classics. A number of them have themes, and in the day, some of those themes raised eyebrows! Not the bloody gore/splatter of today, but just well done, and in B&W.
I realized that I am a big horror fan myself. It's the scary video games that freak me out more than the movies. The Paranormal Activity movies are good though. They are so realistic.
