for me, Higurashi is a great anime, more like psychological that horror, and i mean that just when you get used to the characters and you get attached to them, you get to know their background, they have to fuc*ing die!!
and no, not so much blood, and it also has slapstick humor in it(well, not much, though) and some pretty funny situations... i won`t tell which, just watch the anime... ^_^
