At first, Shiki feels boring. Nothing really happens in the Sotoba village and, when vampires come to live there, no one bats an eye. When people start getting mysteriously sick and die, people first worry then, finding no easy to swallow explanation, get used to it. When strange things start happening, people invoke reason and "the way things are" and refuse to see what's there in front of their eyes.
There is something terribly creepy in Japanese horror because, at the heart of their culture, normality is paramount. Things have to be in order, regardless of the desires of individuals or even whole social classes. The cleanliness and politeness of the Japanese, that we Europeans love to admire, are mere consequences of this oppression, which happen to be positive. Yeah, that's a thing in almost every culture, especially those which boast liberalism and freedom (God forbid you are not a freedom loving liberal!), but the Japanese take it to a different level.
In truth, if they would have left it at that, a small village committing suicide by denial, it would have been powerful enough, but Shiki just starts from there. Because you see, when people turn to vampires, they don't get possessed by demons or lose their feelings or turn into instant psychopaths. Instead, they retain their personalities, but have to deal with the unstoppable feeling of hunger for human blood. And once they get it, they do what people do best: rationalize it somehow as a positive, necessary and unavoidable thing.
So my advice is to stick with the story, even if it starts kind of slow and obvious. There is a lot to unpack, even if basically it is a harsh criticism of the small mindedness of people. I liked it a lot. You can read the manga online or watch the 22 episode anime. It is a complete story, there are no sequels and there is no point in there being one. I watched the anime and I liked it. I think in this case, it might be better than reading the manga.
