Story 1: Wonderful narration! I hope I don't get cursed and nor do the producers(just kidding!) I really like the way it shows ancient Japanese folklore and culture, it's superbly portrayed and scripted with additional trivia.
Story 2: Inevitable plot from the beginning. Slightly boring, could have been condensed into fewer episodes. Didn't really like the story, hence I'm giving it a lower overall rating .
Story 3: Amazing! the theme is about how humans can be more cruel than demons and things like morality are shown in a very creative yet smooth way.
Overall: It's a nice series of stories, really like the art and sound, it's pleasing and has a grace to it all which is difficult to put into words. A good traditional horror in short!
