Movies

So, what's the deal with all of the gory, killing, demonesque movies that are coming out? Seriously. Each time I rent a movie, I see previews for movies like this. What is wrong with the people making these movies and why do people go and see them? There are movies about zombies, people being possessed by demons and movies that have tons of blood and gore. It's just wrong! Movies like that should not be made and it saddens me that they are. It really makes me sick.
