"Of course, it helps that human beings are just inherently fearful of the dark in the first place, so horror movies unsurprisingly tend to take advantage of that truth. It's commonplace, it's the norm, it's to be expected.
Which is why it stands out when a film/filmmaker takes the opportunity to deliver scares, terrors, and unsettling beats beneath a blanket of bright sunlight. It's more difficult to squeeze scares from brightly lit scenes and sequences, so it's worth celebrating the movies that nail that daytime horror aesthetic. The films below don't necessarily take place entirely during the day, but the bulk of their running times do with memorable scenes looking for and finding things to unnerve us far from the darkness."
