What do you get when you get the Crypt Keeper in an animated series? A horror animated series, that's what!
I personally like the series because it's funny and it's scary at the same time (but not too scary). I like how the characters always happened to learn something int he end (while others never lerned their lesson). Plus, the way the Old Witch and the Grave Keeper always trying to steal the show from the Crypt Keeper, that always cracked me up. Still, he managed to always come up on top of them with some very wacky schemes.
It's not perfect, but it's very good, and I do not mind to watch the series again and again, because the animation is good, the voice cast is great and well, I love every series where we get a good scare. 9.5 out of 10.
