"In the realm of genre movies, megalophobia reigns supreme. Look at Ridley Scott's Alien. Sure, the face-hugger and Xenomorph are scary, but what takes our breath away first? The gargantuan "space jockey" that the crew of the Nostromo discovers in a cavernous, decrepit spaceship on a desolate moon. This same sense of megalophobia is what makes Godzilla or Jean Jacket in Nope so frightening: it puts into painful perspective that our place at the top of the food chain may only be temporary.
But what about in the reverse? Is microphobia just as scary as megalophobia? Yes and no. Sure, pint-size terrors don't inspire the same cosmic horror vibes of a creature like Cthulhu. But the micro-monsters do have something up their sleeves that the mega-monsters can't match. It's in their ability to seamlessly blend in with our everyday lives, whether that's in the form of a killer cat, a possessed doll, or something completely beyond the pale."
