Space Cases was like Star Trek: Voyager for kids. It was around '96 I think, which was probably the last good year for Nickelodeon. Angry Beavers was pretty good, but once that show started, it was the beginning of the end for Nick.
Personal favorites:
The Adventures of Pete and Pete
Rocko's Modern Life (Best Nick toon by far)
Most of the shows were seem alot better now then they were then, just because of the whole nostalgia factor, but those two were and still are two of the best shows ever. I wish I got Noggin.
