I recently downloaded the first 2 seasons of the real Ghostbusters animated series.
While it is not nearly as good as how I remember it, it was, in fact, one of the smartest and best written kids shows in the West. The plots themselves are rather simple, and contrived, but some of the detail in the dialog is quite cool.
I mean, come on, how many other Saturday morning kids cartoons mention Cthulhu, while in the same episode feature a character named Clark Smith? They also name check Samhain, Citizen Kane, and a host of other more adult themes and things.
Pretty cool.
The animation isn't half bad either. I always liked DIC's work.
