Yeah, but who still remembers Candle Cove? That show was awesome, although I only saw maybe three episodes...
You... I like you.
I don't remember much of Bucky O'Hare other than the awesome NES game that was made based on the cartoon. You got to play multiple characters even though the robot was the only one worth playing. I DO remember the show being pretty hard sci-fi (I.E. very, very detailed and expansive) for a kid's show which is something you don't see a lot of today.
Batman: TAS still holds up well. I recently got the entire series, and after ripping to my hard drive and putting it in the correct viewing order it was awesome to see again.
I think Batman: TAS, Samurai Jack, Dexter's Lab, and The Powerpuff Girls are the four cartoons I remember as a kid that still hold up today.
