While anime is a flexible medium, it's notoriously fickle when it comes to horror, often veering into horror-adjacent topics but not fully committing. With horror providing a fascinating spectrum through which viewers can feel dread, terror, or disturbed, anime has had numerous opportunities to strike that balance over the years.
Some horror anime are dark to the point of being gratuitous, but that's part of their charm. They're more concise than the usual offerings due to their niche nature, lasting one to two cours each, providing a perfect opportunity for a binge. Coming up to Halloween, any of these dark horror anime would be a perfect addition to the watchlist.
