Halloween is just around the corner (it literally is, go look) and that means its time to dust off all the scary movies and hide behind the couch while you try to watch them. But not all horror movies are really scary. A really scary movie is one you can barely watch and then later makes you leave the lights on when you go to bed.
What makes a movie like this?
Many newer mainstream horror movies aren’t like this. They lack that lingering horror that many classic movies have. It is the unknown that makes you scared. When there is an evil murderer on the loose (which seems to be a classic horror plot) it is more scary if the murderer is a tall shadow that hides around corners then if he (or she) is seen in full from the beginning (in a mask, or occasionally you actually know who the murderer is). This is because only your mind knows what makes you scared. If you see the murderer then your mind knows what is happening. If you only see a shadow or get the suggestion that there is something hiding around the corner then your mind creates something which is scarier to you then anything that can be created by something else.
Let this be a lesson to movie writers, only you can truly scare yourself, there is always an initial fright but true horror lasts longer then the movie.
