What are your favorite horror movies?

Since it's October again and Halloween is upon us I'm curious whether other people on this site love a good horror flick.
I've been a horror fan for as long as I can remember being a film fan. It's a genre saturated with absolute garbage, but there are some real diamonds to be found as well. I'm not much into "gore" flicks - not because it disturbs or upsets me, it doesn't, but because I consider most of them to be childish shlock - but I love a good classic horror movie with a solid atmosphere and vibe.

Here's a list of horror movies I consider to be entirely worth checking out;

The Texas Chainsaw Massacre (1974 original)
Mulholland Drive (arguably more mystery thriller than horror, but its vibe oozes dread)
Lost Highway (same case as Mulholland Drive)
Eraserhead
Inland Empire
Twin Peaks: Fire Walk With Me
Silence of the Lambs (also debatable if horror, but it's included afaic)
The Thing (1980 original)
The Exorcist (1973 original, but Exorcist III is one I consider to be very good as well)
Halloween (1978 original)
Suspiria (1977 original)

I got to admit I've not yet watched A Girl Walks Home Alone At Night, but I've heard good things.
I recently watched The Black Phone and I quite liked it. I didn't find it particularly creepy, but Ethan Hawke is great in it and it has a good vibe. I liked the IT remake as well.
For some reason I never really vibed with Let The Right One In.
There are also a lot of movies from the 20's and 30's I should still give a shot.

Definitely appreciate the classic of the '20's & '30's. I also recommend taking the time to watch A GIRL WALKS HOME ALONE AT NIGHT. Sorry to hear you didn't enjoy LET THE RIGHT ONE IN as that blew me away the first time I watched it.

I do think Let The Right One In is a good movie when it comes to the drama aspect, but I don't find it all that creepy or eerie. I think I still have it in my collection though, so I should give it another watch.

When it comes to acclaimed modern day horror, one director whose movies I don't appreciate as much as self-proclaimed critics do is Jordan Peele. I mean, his movies are well-directed, the plots are original and the acting is usually very good, but they just kinda fail when it comes to the "horror" side of things. They aren't remotely creepy, scary or disturbing.

Agreed as his films are more psychological than physical horror, which I'm not a huge fan of psychological horror. Plus, he's a race-baiter and overrated IMO. His first film GET OUT is a masterpiece, no doubt about it and it's my favorite film of his. US I only saw once in the theater and never had any intention of seeing it again as I found it to be an unworthy follow up to GET OUT. NOPE was ok, better than US but still lacking to GET OUT. I've said it before and I'll say it again, Peele may be experiencing the M. Night Shyamalan effect where he peeked with his first entry and nothing he subsequently puts out will compare with it (a victim of his own success).

Among the classics:

Bride of Frankenstein
Nosferatu (1922)
The Mummy
Dracula
Werewolf of London

Among the postwar fims:

The Thing from Another World (Nyby/Hawks)
The Thing (Carpenter)
Bram Stoker's Dracula

Special mention to:
The Hunger (1983) All style, little substance--but the style...an elegant vampire movie.

In more or less date order from listings in the Horror film Wiki:

THE WOLF MAN (1941)
THE BEAST FROM 20,000 FATHOMS
HOUSE OF WAX
IT CAME FROM BENEATH THE SEA
INVASION OF THE BODY SNATCHERS (1956)
THE FLY (1958)
THE TINGLER
PSYCHO
THE PIT AND THE PENDULUM
NIGHT OF THE LIVING DEAD (1968)
THE EXORCIST
ALIEN
THE HUNGER

Glad to see Carpenter's The Thing getting a lot of love on here. One of my all time favorites.
