I usually keep up-to-date with all the horror news, and make sure Heaven of Horror share the best and latest trailers for upcoming horror movies. I love all kinds of horror. My love affair started when I watched 'Poltergeist' alone around the age of 10. I slept like a baby that night and I haven't stopped watching horror movies since. The crazy slasher stuff isn't really for me, but hey, to each their own. I guess I just like to be scared and get jump scares, more than being disgusted and laughing at the grotesque. Also, Korean and Spanish horror movies made within the past 10-15 years are among my absolute favorites.
