20 Horror Monsters That Were Scarier Before You Saw Them

The Strangeness begins with a group of explorers venturing into an abandoned gold mine in search of riches. Trapped underground, they find themselves being stalked and gruesomely picked off by a gigantic cave worm (nicknamed "Binky" by the film crew).

The worm injects its prey with a corrosive acid, reducing them to liquified gloop within seconds. Though the worm remains unseen for the longest time, there's a constant state of dread, especially when the characters find what's left of their friends.

Sadly, all that fear dissipates when the worm finally steps out of the shadows. Even though the tentacled behemoth has a cool Cthulhu-like design, its head has (how do I say this?) a vaginal opening, which is more distracting than teeth-chattering.

Somehow, that's not the worst part. Rather than using an animatronic or a costume, the worm was brought to life with stop-motion. Although there's nothing wrong with this technique, the worm moves with an unnatural jankiness, which looks unbelievably amateur. 

While it's attacking, there are times where the worm's victims are portrayed with stop-motion models, which look so fake, you'd swear you were watching a spoof.
