It's pretty scary, not because there are demons or ghost with bloody appearance or scary faces but it is because the simple, mundane things in every day live could be dangerous and nightmarish if you are not careful enough. And there are also superstitions which most of you choose to ignore and turns out that is a foolish thing to do.
However, there is some good moral inside each story and it can be a good thing for kids; not too young though, just a lil bit younger than teenagers.
All in all it's not a real flop; easy to grasp and has a good moral message. And it's creepy enough to pump up your adrenaline so it won't be a dissapointment for those who are looking for the tension. The art though is rather messy for me but I thinknthe messy art might be the adding point for its creepiness.
