I’m not especially fond of horror as a genre. Maybe it is because horror is not often the best written genre in cinema. Maybe it’s because I really don’t enjoy viewing things that are gory.
That being said, I do find that generally horror is a highly moralistic genre (maybe the most moralistic genre), since it tends to portray good and evil in the starkest terms possible (there are typically no fine lines between ugliness and evil, for instance, in horror). I tend to find this vaguely interesting, as I am drawn to works that are concerned with morality and ethics in the philosophical sense. However, that also being said, I more often find that revenge films and even exploitation cinema are more interesting than the typical horror film in exploring these ideas (give me Quentin Tarantino over Clive Barker any day of the week).
