User blog comment:Zoether/Do you want this to be to the last season with the original cast?/@comment-5928665-20131002231330/@comment-23995441-20131002235133

Im talking about the ORIGINAL cast not the TDROTI cast. Everyone in the original cast has already been built up to their full potiental. It's just some of the terrible character *cough Katie & Sadie cough* were just too flat of characters to get any major development.

"Many shows can last for over a decade while only focusing on about six or so."

And those shows have gotten significantly worse. Watch any show past the say.....7th season like that around the time Flanderization begins to set in & you'll notice how unenjoyable the show has got [examples include: Spongebob, Family Giuy, Pokemon].
