I ask cause alot of shows that last to long suffer for it, such as The Simpsons, Phineas and Ferb, Family Guy, Spongebob and The Fairly Oddparents. Personally I think that The Simpsons and FOP were fine even with there long years, and the irony is that most fans beg the creators to make more even if it leads to the show getting ridded by fans saying how it isn't as good as it use to be. So what do you say, is a series lasting long good or bad for it?
