The aliens scattered around the Alien series are absolutely terrifying nightmare creatures, and many people have come to think of them this way. However, the question remains: are the Alien creatures the scariest horror movie creatures? In this context, “creature” just means any unique concept that a movie invented or put its own twist on. The good news is that whether you feel like they’re the scariest horror villain or not, there are plenty of others. From this list of the horror movies with scariest basements, here are the movies that have the most interesting creatures.

Scariest Basements and Crawl Spaces in Movies & TV Created By: OhioBasementAuthority
The Exorcist
You might argue that The Exorcist is a supernatural struggle between a priest, an individual child, and a creature that comes straight from Hell. However, it’s a bit more complicated than that because The Exorcist all but invented supernatural horror. Although the evil demon from The Exorcist might seem a bit cliché and overdone to you now, it’s a good idea to remember that in its time, The Exorcist was so scary that there were rumors people had miscarriages because of watching it. 12-year-old Regan also finds an Ouija board in her basement in this movie, and that’s about the scariest basement event to happen.
Psycho
As with The Exorcist, Psycho can seem very cliché and not enjoyable when you give it a cursory glance. Even though many pieces of the movie still look incredible due to enjoyable writing and high-quality directing, that doesn’t mean it always looks good to a modern audience. However, one important thing to realize is that Psycho also essentially crafted large swaths of modern horror. It’s basically the reason people have the concept of a serial killer genre of horror movies. Plus, in one of the most recognizable moments of Psycho, the main character goes down to the basement, where she finds Norman Bates’ mother’s mummified corpse.
A Quiet Place
Of this entire list, A Quiet Place is one of the movies that has terrifying creatures in it that seem surprisingly similar to the monsters from Aliens. They obviously serve different purposes in the movie and have a different driving characteristic, but they’re also interestingly similar. That means if you love the characters of the aliens from the Aliens series, you might want to look into the character design from A Quiet Place. An especially terrifying basement scene occurs when one character goes into the supposedly “soundproof” basement, but quickly gets chased out when a pipe bursts.
The Grudge
In The Grudge, the bad guy is actually a curse. Specifically, this is a curse that, should you die in the grip of rage or sorrow, you become a type of spirit that attacks others. Although The Grudge didn’t get a great critical response, it did get an incredible amount of money back from the Box Office. That commercial success is an important part of why many people still see The Grudge as being a guiding light to the horror genre as a whole. It also has a pretty terrifying basement scene, where Muldoon visits the basement armed with only a flashlight.
A Nightmare On Elm Street
Technically, the bad guy in A Nightmare on Elm Street is just a man. However, he’s not really just a man; A Nightmare on Elm Street redefined the idea of “just a man” and crafted its own terrifying creature: Freddy Kruger. This man is much more than “just a man,” and his horrific deeds absolutely make that obvious. When he pulls people into the “dream world,” he sometimes brings them to his boiler room, or “nightmare factory,” where he tortures and kills people.
Conclusion
There are a lot of interesting and terrifying creatures available out there in the world of horror. Don’t feel like you have to go ingest some particularly boring horror. You can find all sorts of horror available through different movies. Consider watching one of these next time you have a family vacation and you want to experience a brand new horror style that you don’t get from Alien: Covenant.
