I suppose I was thinking more along the lines of these shows being overlooked especially compared to the shows of the classic 90s and the 2010s recovery eras since these shows took place before and during CN's dark age of live action trash; they don't get discussed or even mentioned as much compared to shows like The Powerpuff Girls, Courage the Cowardly Dog, Adventure Time, or Steven Universe. This probably doesn't make them "underrated" though.
Looking back now; indeed Sheep in the Big City, Time Squad, Whatever Happened to Robot Jones?, and Class of 3000 are more fitting examples.
