I guess you like horror stories, or stories with ghosts
since you watched Mieruko-chan too last year.
I'm curious ... What scariest movie have you ever seen?
In truth growing up I was somewhat of a pansy when it comes to scary movies and somewhat still am so I don't really have a "scariest movie". I mean I was 11 when Blaire Witch Project came out and I remember watching it with my mother, and by "watching" it mostly covered my face with Mum's arm or something like that. While there are those who "enjoy" being scared, I question why people enjoy being scared.
But as I grew up I realised I don't find most horror movies as scary but I still don't really bother with them. I mostly like Yami Shibai because of the suspense and storytelling than desire to be scared. I also like Mieruko-chan because I find it rather different than most anime I've seen out there.
When I was a kid growing up I liked anime, I found it a different and exotic form of cartoon but anime was rarely shown on TV. Now that I can watch anime on the internet I find most anime recycle the same tropes that I rarely find anime I enjoy. Common tropes such as harem with protag where every girl desires him but still a whiney lil pansy who dare not grab at the low hanging fruit despite said fruit practically being picked and served for him, anime set in some fantasy land, often with RPG elements for absolutely no reason. Like seriously, why should I care if a sword has +2 damage when your mother is an OP milf, or girl with impossibly high defence or magic stats or whatever RPG mumbo-jumbo when we're watching an anime and not playing a game. Or slice of life anime about japanese school girls doing japanese school girl things, how many japanese school girl anime do we need?
And of course anime set in dystopian future with edgy protagonists. Often dystopian due to deep sci-fi lore reasons that I can't get my head around. Probably to do with demons, aliens or monsters created from human folly.
I know regular western cartoons aren't that diverse but I rarely find anime I'm interested in because I probably seen the tropes done to death or it's just over my head.
But there are a few anime I genuinely like, such as Jojo Bizarre Adventures, OnePunch Man, Zombie Land Saga (Season 1 opening reminds me of THotD for some reason), Demon Slayer (granted, usual tropes but well animated and good story) and there is probably other anime I like that I forgot to mention.
As for "popular anime" like One Piece or Naruto, no, just no.
