I definitely think movies get scarier when you're older because you know some of the stuff actually happens, also you have a greater sense of your own mortality. After 20 I've become a real scaredy cat. I also think some films have become sadder as I have more empathy than when I was younger, for example I cried at the end of sixth sense the umptheenth time I watched it because I suddenly knew what it would be like to lose the love of your life. Ah the joys of a fully developed limbic system.
