The Descent was one of the first films that scared the crap out of me, and is, till this day, one of my favorite horror films of all time (pro tip: don't watch the sequel)
The Shining might be an obvious choice, but I am a Kubrick fan, how could I not love the tense atmosphere he creates.
Of course, I am also a big Ju On fan, and while its a tough choice, I think the original and very first Ju On film, Ju On The Curse, despite only being 68 minutes long is legit fucking terrifying.
You know, what I also like Ju On The Grudge, so whatever.
While I found
Event Horizon, Invasion Of The Body Snatchers (1978), A
Nightmare On Elm Street, and
Hellraiser to be brilliantly made films, they did not scare me much. I do like their entire art design and the story, but I think I am more of a phasmophobe, so non ghost movies rarely scare me (The Descent being an exception of course).
Oh yeah, speaking of ghost film. While I hate the franchise or more accurately the universe as a whole, and I think every other film is just a step down, the first conjuring film is legitimately a really well made horror film and a scary one at that.
While I like David Lynch's
Eraserhead, and the entire nightmare like presentation is amazing and it is one of the best films ever made in my opinion, I still found it more disturbing and eery than outright scary. Same goes for Jordon Peele's
Nope. My favorite Peele film and really amazing film with really amazing tension, but it is more of an adventure-esque film I would say (despite taking place in single location) than straight up horror.
Another exception for a non-ghost horror film that scares me though, is 1974's
Black Christmas.
Like, it is the only slasher film that ever scared me per se. Most slasher films are more fun than scary, but Black Christmas was legit terrifying with not only terrifying implications but also terrifying moments. The scene with the eye staring from the gap of bed, the scenes with the first person tracking shot, and that final long tracking shot going from the bedroom to the attic is legit scary. The entire atmosphere it creates was legit terrifying to me, and despite me being a 5 ft 10 inch fat boi, I felt like a helpless woman throughout its 98 minute runtime.
Another non-ghost horror film that managed to scare me (and to be honest, is also one of the most beautiful looking films I have ever seen) is Francis Ford Coppola's
Bram Stoker's Dracula.
While its not outright scary all the time, whenever it decides to be, boy it feels straight out of a nightmare. There is a scene involving a first person tracking shot, and that scene still this day scares me, and that entire werewolf esque form of dracula is also well done. It is also a legit well made movie that gets vampire movies right, mixing gore, horniness, and nightmarish vision in a perfect blend. While I haven't seen any of his acclaimed films after this like The Rainmaker or Tetro, I do think Dracula would have served as a really good retirement film from Coppola if he chose to, for this is his magnum opus, and outside of weird Keanu Reeves acting, it really achieves every mood and atmosphere that Coppola wanted to and that with some really good production behind it.
I have similar feelings about Kwaidan as well.
And last, an oddball entry that not only impressed me, but also scared me, and that would be
Hikiko: Toshi densetsu monogatari (2008), which is this intentionally ps2 graphics level animated horror film that has the same tense atmosphere and vibes I got from games like Siren. Especially the final scene of a guy taking a dead body out of a locker sent shivers down my spine.
Seriously, don't let the ps2 graphics or odd way the character moves deter you away from this short but amazing film. I feel like that uncanny movement actually adds to the tension.
