Horror

Any Adam Curtis documentary.

Zeitgeist 1

Bring Her Back was fucked.

Not a fan of terror, but saw The Ring with friends and it had some memorable jump scares.

Now what really scared the shit out of me and probably created some trauma was the witch from the Wizard of Oz. Also that wolf in Neverending Story. Probably because I was 8 years old.

I'm not a huge fan of horror (I came across this thread in my all feed), but when I was in my teens I saw some random movie on TV that scared me freaked me out for quite a long time afterward. Unfortunately I don't even remember the name, but maybe someone here will know what it is. From what I recall, it took place in a carnival, and the "monster" was some horribly deformed guy that had eyes that were far apart on his head. He would lurk around inside carnival rides and kill women visitors.

Smile.

I don't know about scariest, but Ari Astor's movies are their own category of emotional horror. Worth a watch, but I will never rewatch one lol. Heritage and Mid Sommar.

Cujo. The premise is so real and absolutely terrifying. It was legit the only movie I had to pause and take a break before I could finish it.

The Day After (1986).

It legitimately broke me.

Not strictly horror but Srpski Film. It’s… yeah… nothing needs to be said about it.

As an adult I generally don't really find horror all that unsettling.

Some that I don't think have been mentioned:

Speak No Evil / Gæsterne (2022) - Even before things really escalate, there is a very uncomfortable atmosphere.

Audition (1999) - If you do watch this one, go in blind and do not look for additional information.

Salò, or the 120 Days of Sodom (1975) - This is more of an audio/visual experience than a horror movie.

As others have mentioned Possessor (2020) can also be very uncomfortable in a more implict way, both the core themes/plot and the depressing dystopian environment. Infinity Pool (2023), also by Brandon Cronenberg, has some of that, but it's not as good as Possessor, IMO.

I feel like movies by Michael Haneke would make me uncomfortable (Funny Games reminds me of Speak No Evil), but I've never gotten to watching any of Haneke's works.

I feel like almost everyone has this one movie they watched (probably too young) that haunted them for days or weeks after.

For me it was IT (1990) when I was 13. I only watched the first movie and it scared the shit out of me. More than a year later, I forced myself to watch the second movie to finally get closure, and it actually helped a lot! But mainly because the second movie is pretty bad, and the ending is the worst (but I was thankful for that, haha).

Since this movie I knew, it is not the type of movies with jump scares, gore and graphic violence that scares me, but the ones that tickle my lively imagination (Blairwitch Project, Paranormal Activities and the like)

In my list of scariest movies of all times, I also have REC and Event Horizon.
