I think people who have experienced genuine horror for real do not find horror movies entertaining.
Its a luxury to be able to watch violence and evil as a form of entertainment and enjoyment. If you lived in Iraq or Afghanistan or anywhere where evil and violence were a part of daily life you might want some other form of escape in your spare time.
Not really. I'm in Afghanistan living in a military base and myself and plenty of soldiers and contractors enjoy to watch horror movies, or violent movies in our time off. And we get attacked almost on a daily bases with bombings or rocket attacks so violence is pretty much a part of our daily lives. Now the afghanis might be a completely different thing, they don't have any tv's in their houses. So to the afghanis that don't even have tv's of course they are not going to see it.
But I'm sure if an afghani were given a chance to see a horror movie he would definitely sit down and watch it. There are some local afghanis that actually work on base and when they walk by a place with a tv that's turned on they stop and watch it in amazement.
Liking horror, or comedy movies has to do with the simple fact that people are different. Therefore different people like different things. There's nothing wrong with someone who doesn't like horror or violence type movies. Just as there's nothing wrong with someone not liking comedy or romance type movies. It all boils down to personal preference and nothing else.
