Today's theme happens to be zombies. I'm not really a fan of how they treat them today since they've made them out to be really what they aren't. The zombies that are popular today are actually more akin to revenants than to zombies. The current incarnation has much more to do with movies than actual folklore and seems to be an excuse for gore than real terror. Even vampires have gone from being revenant-like beings to more like romantic predators.
It's like modern storytellers don't know how to scare people anymore. This is most evident with ghost stories. Since Poltergeist people think ghost stories have to have a sense of danger to them but it was simply the sheer nature of the ghost that made them scary.
A ghost doesn't have to kill. It only has to warn someone that they will die. The mere thought that someone will die through accident or natural means is scary enough. The ghost doesn't actually have to do anything. It's those ghost stories that merely suggest a supernatural element that are often the most effective because it suggests that the world may not be as safe and comfortable as you think, but at the same time it offers a hope in something beyond death.
