I rewatch it every fall. People don't exaggerate the greatness of this show. I highly reccomend it. My mother, who barely watches any cartoons or content for younger audiences, was surprised by how much she liked it.
The characters are very likeable, the story is great, the animation is stunning, etc.
The show can be creeping at times, but not too much where it would scar a child. (Reccomend age of watching is 8 or 9 years old). I think of it as if scooby doo was on one scale, and coraline on the other, then this show would be in the middle.
