Man, it feels like I did this forever ago. BUT ANYWAY.
Anecdote: I remember seeing this show for the first time around the age of 4- which was a miracle in some sense, since my parents didn't really like me watching cartoons at all (see how far that got them; nothing like holding a degree in something they tried distracting you from for years). That aided by the whole concept of a supposed middle-aged ghost hanging around, and often onto, a teenage girl? Well, the show must have been too charming for my parents to say "no".
