Poor decisions and bad luck are contingencies of most horror films.
Fear is that feeling that we mentally grasp but emotionally are oblivious to. Horror movies temporarily create that emotional experience without devastating consequences. The thing that will piss me off most though about horror films is how silly and stupid some of the characters can be. I mean what person in real life do you know is running around wearing a thong and t-shirt in 38 degree weather? What person do you know is going stop on a dark road to investigate a strange creature that ran in-front of their car? I mean some of these horror films take a scary though and run so far with it that it will literally piss you off. Most horror film plots aren't even realistic. There's no real fear sometimes if the story line isn't realistic. Sometimes you'll see a good horror movie and it will take you into a completely different mind set about the world we live in - like is this something that someone would really do? Then you think - well if someone crazy see's this movie - then they'll have the idea to actually do it. So I know a lot folks who just don't do horror movies at all and surprisingly most people avoid horror movies.
The psychological and physical traumas, the gore, the anticipation, and the endings with no definite resolution create something unpleasant movie goers. It all circles back to the FEAR again. Some people reject fear for the same reason others crave it. Fear is a rare, infrequent experience. The strange, exotic feeling is like a drug. Some try it for the first time and are hooked, while others choose to ignore it or hate that it causes them so much anguish. Horror movies always provide a sick sense of comfort that we can be scared while not needing to feel anything emotionally for the victim. After all, that's only an actor getting impaled - not a real human. In some ways, horror movies mitigate life's difficulties. When you're watching sorority girls accidentally kill a freshman, the anticipation of a college acceptance letter suddenly becomes less engrossing right? or If you see a man poisoning folks at his restaurant, eating at a little diner will all of a sudden seem daring and risky.
Ultimately, the psychological thrill is what captivates the audience. We feed off these emotions and the adrenaline rush. Perhaps there is some elaborate scientific explanation as to why horror movies are popular with some and despicable to others. Regardless, horror movies are a form of art. To create the perfect horror movie is not an easy task. Too much gore disgusts the audience; an ending that answers all our questions won't leave us disturbed; too many mythical or fantastical elements destroy the movie's credibility. Now the secret that Hollywood doesn't want us to know....(wait for it).....The art of a horror movie is all in the music. Next time you watch a horror movie - pay close attention to music. Listen to when it starts, how it sounds and most of all - how it makes you feel. Try this little trick - silence the sound and just watch the pictures - I promise the fear of some one jumping from a closet or someone running out of the woods with a axe won't scare you half as much as when the music is playing. Horror Movies are an amazing genre and there are thousands if not millions to choose from. Try a foreign film, particularly a Japanese film - they are five times scarier that American made movies and look out in the credits of American films for Japanese producers, writers or executives - they are the true master's of horror.
That's my opinion and I'm sticking to it,
