I couldn't get into this one personally, because there are all sorts of inventions and ways we could do that would explore the holes without ya know... jumping into them?
Like, I dunno, throw a cell phone camera in there and see where it goes?
I guess the "horror" was the mass hysteria that caused people to mentally link themselves to a hole and think they had to jump in. But psychology doesn't work like that, as far as I'm aware (and there's some psychological horrors in the real world, like schizophrenia, that do scare the bejezus out of me).
But yeah, I realize everyone else thinks its a masterpiece. But... I just couldn't take it seriously. But give it a try, maybe it works for ya!
I haven't actually read anything he's produced but I got very interested after playing World of Horror which is heavily inspired by his work. I feel like I've already seen some of the creepy stuff from The Enigma of Amigara Fault and Uzumaki so I feel less interested in starting them(Or at least starting WITH them). Do you have a favorite that isn't one of the popular memes that you recommend?
Tomie isn't as meme-ified as Amigara fault, or as widely adapted as Uzumaki, but is another of his bigger works, would recommend!
Also, you may have seen a few images from Uzumaki (the hair, the face) but the story is quite long and really unsettling! Would still recommend giving it a read.
