I'm a bit of a pussy and am slowly getting more into horror, but psychological horror I find super interesting. It doesn't always freak me out (Silence of the Lambs is supposed to be psychological horror, but it came off more as a thriller tbh, I think One Hour Photo fits the bill more), but I enjoy works that explore the psyche and its fragility and how it can be manipulated by anything. Horror video games seem to be oozing with this, but I'm not as inclined to play them for sissy reasons. Corpse Party was the closest I got, and Higurashi barely counts as a "game" but the sound novel is intense and legit gave me nightmares, I love it. (The live-action movies sucked.) Giant animal monster movies are probably my favorite B-horror movies if I had to pick a genre, but I don't watch them much anymore. Used to when I was younger, especially when Blockbuster was still around, in which case Them! and Godzilla are my go-to favorites, with Anaconda on the occasion.
For more proof how much of a fucking pussy I am outside of the fantastical elements, I still have of yet to watch J-horror movies despite the genre interesting me. I've seen the American take on The Ring, but Ringu eludes me. Maybe it's because I don't wanna watch it and Ju-On alone for some reason, in which case make fun of me for it, especially since I had watched The Exorcist alone at night and came out of it just fine (fuck that blood-letting scene, though, just gross). But then again, something as stupid as Frogs somehow managed to freak me out years ago, so maybe I don't really have an excuse.
Also hot take, but The Babadook was honestly a pretty good movie. The Internet did stupid shit to it, unfortunately, but when you take the movie at face-value, I thought it was a good take on personifying grief and being freaky about it. Dad will sometimes reference it at random, but that might be because that was one of the few movies I actually willingly sat and watched with him in the last few years.
Lights Out had so much potential since the short film is actually great, but holy shit the executive meddling shows. Test audiences can be dumb motherfuckers at times.
