1. Halloween (1978)with the ones I've seen (11 out of 20) in bold print. I have Halloween, Jaws, The Exorcist, Rosemary's Baby, Suspiria, Friday the 13th, The Texas Chainsaw Massacre, and A Nightmare on Elm Street on the shelf waiting their turn. There are so many of these lists. I wonder if anybody has ever collated a lot of them to see where the major points of agreement are. Surely someone has. I mean, this is the internet!
