Bugs Bunny and the rest of the Looney Toons gang. Something for everyone there.

Jonny Quest, which I watched as re-runs in the 70s.

Rocky and Bullwinkle, especially Mr. Peabody and his boy Sherman and the Way-back Machine.

I, too, was addicted to Star Blazers and I actually have the first four episodes on VHS. It didn't age well...

As for current stuff, I love South Park. The crappy animation and unintelligible voices are part of the joke. The other one I like a lot but rarely get to see is Foster's Home for Imaginary Friends.
