Also, I fail to see how longest running relates to quality in any way. The absolute best season of television ever made was True Detective season 1. The fact that there are only 3 (soon to be 4) seasons in total or that the other seasons are shit doesn't in any way diminish how amazing season 1 is.
not saying that there is not reason for people to like watching the show, but I just think cartoons should be in a separate category.
As far as longevity goes, it is an unequal stage. They could keep the same show and characters going for many decades whereas that is not the case with regular shows.
I have watched just enough to know I personally dont care for these newer prime time cartoons. Last one I liked was Johnny Quest, but then I was around 10 at the time.
put some good hearted light on the CFL in a few episodes reaching millions to probably google the CFL down in the States and elsewhere to see the reference .
