"Jonny Quest" was one of my top 3 fave cartoons, right up there with Bugs Bunny and Pals (I also loved "Space Ghost"). I still watch it when it pops up on the odd cable station. The stories were good, though in some cases a little harsh. Vengeance, red in tooth and claw. I doubt it would pass as a cartoon these days, but it would make a dandy written YA series.
