What scares you?

Why do we like scary movies? I think we like scary movies because it stimulates our brains and keeps us on edge. I know from watching horror movies that this does this to me and i know my friends have said that scary movies do this to them to. Scary movies have been around for a long time and have gotten scarier over time as have the after effects to make a movie scarier. If you compare the music from horror movies from then to now the music has changed for the better and another huge reason for this is the timing and editing of music. If movies did not add suspenseful music or good after affects i don't think a movie would even be that good. Try watching a movie without sound, i guarantee you will not get scared at all.  That shows how important music is to a film and it needs to be good in order to make a movie good. A example of good music in a horror film is Insidious, that movie had such great music that at certain points the music would give you chills. I think music can make or break a movie so if it does not have good music, it will not be a good movie.
