I love horror movies, as long as they aren't just excuses for the director and F/X people to practice grossing me out.
I don't mind appropriate violence, as long as the violence isn't the point.
Give me witches, vampires, ghouls, monsters of all varieties, and I'm okay. However, I don't enjoy horror films with serial killers. That's too real. Horror requires a healthy dose of unreality for me to enjoy it.
Enjoy? Yes, I enjoy being scared, as long as I know deep down that what frightens me on screen doesn't exist in real life.
