I remember as a kid. There were lots of shows that i did not want to end. I wanted them to keep running forever. But, Now that i'm older. I can see why its a bad thing for shows to keep running for so long. Spongebob is the biggest example of that. It was good until after the movie was made. I think the movie would be a great ending to end the series. But, Nick was to busy being greedy and forced the original creators to give the show to them and now the show is just unwatchable. I already went though so many reasons why. It is sad seeing good shows end. But, Its better then them becoming on what Spongbob became. Its also better that they don't get continued with a spin off of a whole new show since most creators now a days changes the characters completely usually. I wish Tv companies learned that spin offs and making a new show with old characters just don't work. Look at the Stitch anime. Its another show i can't stand do to them raping my childhood. It should be against the law. Now as you know. Most shows that keep going for so long do go downhill over time. Like Family Guy. The Simpsons. Pokemon. And Fairly Odd Parents and Ben 10. Their mostly doing the same crap over and over again. The jokes soon grows stale and boring, They run out of ideas on what the plot of the episodes should be about. And the characters would have the same problems and would forget about how to fix it. There are some exceptions with the rule. But, The Stitch Anime and The Looney Tune Show and Teen Titans GO is not one of them. It also shows that Reboots do not always work and they should cut out the Reboots. TMNT got rebooted way to many times for me to even count. The Looney Tunes did too cuz they got toned down all cuz stupid parents thought they were to violent. Not all Reboots are bad. But, Its being overused.
