To put together the ultimate list of scary short films, there is bound to be some subjectivity. One of the great things about the internet and modern filmmaking is that putting a horror short film together can be relatively cheap and distribution can be wide online. So there is a lot to choose from. While I try to represent a lot of different types of horror-lovers who like a lot of types of horror (jump scares, morbid creepiness and dread, blood and guts), where they fall on the list is based on my own take on their quality, effectiveness, and oftentimes how popular they have become amongst the horror-loving crowd.
