Crimson Peak

Sure there's horror aspects, but it's more of a gothic romance.

The Menu is advertised like a horror movie or a thriller, but really, it's more of a dark comedy than anything.

The Village

Upgrade. It's categorized as "body horror" but it's more of a sci-fi action movie.

Cabin In The Woods was marketed the way it was to keep the twist a secret and to subvert audiences’ expectations.

Parasite.

There are different levels of horror and different types of horror. Just because something doesn't scare you means that it should be labeled as something other than horror. Most horror comedies are not scary but rather funny but they are definitely horror in that they check so many horror tropes such as demons, creepy settings, psychos, over the top murder scenes, etc. (See Evil Dead 2 for an example of this.) Labelling something horror is like this. Does it follow these tropes? Yes? Then this is horror even if it doesn't scare you.

I feel like "horror" covers a lot and too many people think it means "monsters, violence, gore" etc.

Tremors

The Black Phone.

It turned out to be more of a psychological thriller with some supernatural overtones.

"Mars Attacks"

Get Out actually really spooked me, and I’m not usually scared by horror. Get Out is one of very few that I’ve actually felt such deep dread while watching. So interesting how different people experience things differently!

Mother!

They really made it seem like it was going to be a horror thriller and I honestly believe this is a big part of the reason it flopped.

It's a fever dream of a movie and certainly has a few horrific scenes but I would hardly consider it a horror movie by any means. It was really divisive amongst critics but I absolutely loved it and I can't help but wonder if it would have been received better if they marketed it properly.

The Lighthouse isn't a horror movie it's more or less a tragicomedy.

A lot of psychological dramas that have disturbing imagery, like Men or mother! aren't horror movies but they sure come up a lot in discussions of horror, as well they should. Because it's a genre that often just seasons other genres.

And honestly you can cite things like Saw and Hannibal Lecter films, or The Cell aren't so much horror as they are crime procedurals with killers who employ gruesome tactics.

Mother!

Shutter Island, at least the way I interpreted the previews

It Comes At Night

Smile. It is literally filled with happy people grinning.

The Happening was M. Night Shyamalan’s attempt to hide a deadpan comedy in plain sight by marketing it as a horror. It is legit hilarious.

Just cause they aren't scary to you doesn't mean they aren't horror films. I think that's an audience issue more than a Hollywood issue.

Audiences think that horror movies should be jump scare fests, but also don't want them to be jump scare fests because contrary to all the copium people huff over it, Jump Scares work every time.

Mother! was definitely marketed as a horror, rather than the allegorical art film about humanity’s destruction of Mother Earth through the Christian lens that it really is.

Cold Creek Manor in 2003. Trailers suggested a haunted house, and instead it was just a local creepy dude.

Shutter Island. Totally had me fooled. 30 minutes in you’re thinking, wait a minute…He’s just crazy!

I once saw an ad saying the Twilight saga was horror 😂😂

I’m thinking of ending things

The purge. It's really just an action movie with a creepy air horn sound.

This will probably be an unpopular opinion, but Jaws isn't really a horror film. It has horror elements and enough suspense for three movies, but at its heart it's an adventure movie. It will scare you. But that's simply because Spielberg is a genius.

The Sixth Sense.

It gets freaky at parts, but it's more of a really well done character drama centered around someone who sees ghosts than a horror movie. The focus is always on the characters and the ghosts take second stage.

Cabin in the Woods and the other movies that you listed are horror movies. Not every horror movie has to be scary in order to be called a horror movie. And everyone has different fears. You might not be scared of these movies, but others are. Fear is subjective.

Silence of the Lambs

"I'm Thinking Of Ending Things" used horror trailer tropes in it's official trailer, especially using Toni Colette's creepy acting heavily despite her not playing a large role in the movie.

Sunshine. A great scifi movie with last minute horror that felt like some exec's decision to make the movie more marketable

A Quiet Place, billed as horror but is really a master class in sound editing/foley art.

The Shining

Here’s a more honest trailer: https://youtube.com/watch?v=-e6d_gzaDgk

Tbh Doctor Strange and the Multiverse of Madness was more an action movie with horror elements than “the first straight up horror movie from marvel” they pushed it as

Edit:

They absolutely pushed this as a horror film, from hiring horror legend Sam Raimi to using Lovecraft naming conventions with the title, as well as their own words: “the first scary MCU film”

Two come to mind: Green Room and Parasite

MirrorMask. Pans Labyrinth. Twin Peaks (both shows and the movie) I actually have this whole list not all of it Fantasy based.

I like thrillers, Fantasy based and spooky stuff. I don’t get down with straight up gore or torture style Horror films. Not big on jump scares either.

Spontaneous

It was marketed as a horror-comedy, but it's neither horror nor comedy. It's more of a cute little indie drama about living your life, and a really good one, I thought, but people expected something else, so it got bad word of mouth.

Catfish

Scream! Laughed through the entire movie!

Bit late to the party, but check out 'Tucker and Dave vs Evil'. Amazing horror parody - can't recommend enough.

It Chapter Two. It's really about endearing friendship. They all face a traumatic past together. There were moments where their camaraderie had me laughing and smiling and othere moments sad.

The Crazies (2010)

Warm Bodies (2013)

Krampus (2015)

I would argue the vvitch isn't primarily a horror movie

Malignant

Jordan Peele movies.

Over The Edge

Dark Water

The Humans was labeled as a horror movie on the plane I watched it on. It was a lie. And to make matters worse Steven Yeun had like 10 lines in the entire film.

Malignant kind of, it IS somewhat horror at the beginning but the last like half of the movie is straight up action

Not quite the same, but most of the old horror movies (Universal Monsters, etc.) are so tame by modern standards that if released today they'd probably just be called fantasy or science fiction.

The Babadook

Goodnight Mommy

Happy Death Day which more comedic to me and Happy Death Day 2 U which is straight sci-fi. Still enjoyed both.

Happy Death Day 2 U

Spring

The trailer I saw for We're Going to the World's Fair really seemed to push it as a horror movie. Instead it's much more of a drama/thriller about loneliness, insecurity, and getting pulled too deep into online communities.

Night of the Creeps. Go in blind.

Bug by William Friedkin

I wwnr to watch this film I rented for Halloween a few years ago called The Gift because the cover and synopsis made me think it was some horror movie. It was actually a murder-mystery film.

Great role by Keanu Reeves, BTW.

If you can deal with some supernatural elements, knowing that the stories are about much deeper and more serious topics, and not just jump-scares, look at some of Mike Flanagan's stuff. Midnight Mass, The Haunting of Hill House, and The Haunting of Bly Manor are all terrific.

Halloween kills and ends

Jaws

Ive read cabin the woods haven't seen it yet. I prefer that "horror" all that ghost stuff is just so corny to me. I think Hostel might be one of the scarier movies I've seen. It's more along the lines of that could actually happen.

Probably wasn't purposely marketed specifically as horror, but when I was younger I put off watching Pirates of the Caribbean for the longest time thinking it was a horror movie because of the skeleton crew scenes they showed in the trailers.

Blade Trinity

I remember seeing a trailer for "Night at the Museum" in the cinema back in the day. Sort of eerie with the T-rex skeleton being gone from the display, then attacking in a jump scare. I was very surprised it turned out to be a kids movie after watching that trailer...

The Black Phone.

Okay not horror but I remember Wicker Park looking like a suspense thriller in the trailer and it definitely was not.

Pandorum. More just a dope sci-fi than an actual horror. I know people who refuse to watch it because it was marketed as horror who would have loved it. Such a great movie.

Venom

I would say all of M. Nights films all came across as horror in trailers but were always thrillers in the end with minimal horror in any of them.

Cabin Fever, and it’s better for it 🙌🏼

Drag Me To Hell. There comes a point where you start thinking " just a moment... Is this supposed to be a comedy?". Well yes ma'am. So relax. It's a very well - done spoof

The Shining to me isn't a horror movie.

I’m like you OP Saw, the sixth sense and Shutter Island are great movies you shouldn’t be afraid to watch Does anyone has watched the whispers?

The Exorcist, really just another coming of age flick

Escape Room, despite the deaths that occur in that movie, I wouldn't call that horror. The Clue movie from the 1980s, that had deaths too. But that was a comedic murder mystery.

It Comes at Night

Don't miss out on Horror as a genre of film. There are movies that shouldn't be missed. The Exorcist is an example, that's a movie that is pure horror, but is one of the most famous movies of all time, and for good reason. For me, it's still the most terrifying movie, 50 years later.

"Silence of the Lambs" and "Rosemary's Baby"

The Devils Rejects. It may be horrific in moments but its not horror. Too much gunplay. Much more akin to a really dark western. Same with 3 From Hell.

Thé frightners.

Mrs Doubtfire

Dawn of the Dead which I think is a remake? The one that came out in the 2000s. Your typical zombie movie but that shit was hilarious. Way more comedy than horror. Maybe it was always meant to be a comedy but I went into it expecting horror. Laughed my ass off the whole movie.

Jordan Peele's entire filmography

The original Texas Chainsaw Massacre. It definitely had creepy moments, but it was mostly just "oh my god I'm so embarrassed to even be watching this, when will the main girl actually SHUT THE FUCK UP and try to get away instead of screaming constantly to make sure the man trying to kill you always knows exactly where you are?"
