This is the veil of ignorance you can use when considering what a just society should be like when making decisions like voting without knowing where in that society you would be.

Like most genres there’s going to be some films that connect with some people more than others. The music, setting, characters, story, etc can all weigh in on how effective the scares or laughs or whatever emotional reaction you’re going for are with different audiences. If heredity was too slow of a suspense builder you might want to avoid other similar slow building suspense for awhile and look for more faster paced action horror, comedy horror, etc other sub-genres of horror.
