no, you don't get it..
don't you have children? Or just no imagination?
Exorcist is more horror than gore. I don't think cutting people up and going overboard with the claret makes a good horror. The thought of someone you love being possessed by something totally evil, that's something I find much more horrible. Admittedly if you don't go with the story in the exorcist then it's just a comedy, but the same is true of all the films on this list.
Guess we'll just have to agree to differ....
