All That: Originally very funny and more mature, then became a dull kiddy show before it was cancelled.
The classic Rocko's Modern Life which was hilarious and amazing has been replaced with the annoying and repititive Spongebob Squarepants.
Even shows in the new generation of Nick which were actually cool like My Life As A Teenage Robot, received good reviews and good ratings were cancelled. That seems to be a trend in Nick TV shows, cancel the good shows but keep the bullshit on.
Me: My young friend, you shall never know.
