First of all, let MES say, i agree totally.
In fact, when i registered here 2 years ago today, the first thread i opened was named "New writers", and even discussed CH Greenblatt. So dont worry, alot of us feel the same way you do.
I was totally ready when SpongeBob came back, May 2005. However, i noticed the change 3 episodes into the season. Season 4 was terrible. Season 5 was alright, IMO. Season 6 has been ok. But it will never, ever be has good has it once was. I really think they should have ended it on November 19, 2004.
I also think SpongeBob would be alot better regarded by my generation because of it. Trust mes, I'm 14, we REALIZE it sucks.
Also, one classic writer is still on the team - Aaron Springer. I continually praise him, and his episodes still stick out today among others. But, sadly, he too has lost his touch I believe.
The good writers of yesterday- CH Greenblatt (who, btw, wrote the fourth season opener), Kaz, Sam Henderson, and the rest...have been long gone.
Its time, sadly, for SpongeBob to end.
I just wish Nick wouldnt totally screw themselves over next year with a really bad 10th anniversary.
