That's sort of the thing, innit? As a kid, I did enjoy the re-runs of "H.R. Pufnstuf," "Land of the Lost" (although the updated version was better, IMHO), and my particular favorite, "Dynawoman and Electragirl." Around the age of seven or eight they all fell out of my favor, replaced by G.I. Joe, Transformers, pretty much anything with a gun, robot or ghosts.
Now when I see those shows, they are utter unwatchable garbage. But that's the thing - I have to give credit to the Kroffts for creating shows that did inspire me and hold my attention, at the time. Most days, that's all you can ask.
