I would say the fairy odd parents. I mean, its still going! I thought the series finale would be the liveaction film " Grow up Timmy Turner " , but now they just still continue the series. I find the new episodes to be nothing special anymore and cant understand, why its STILL running. I just cant imagine that its still fun to watch, i mean its the same thing for years. How long does it take for timmy to grow up?
And Spongebob, because most of the new episodes are just strange and disgusting. I mean, i cant understand why its still called a kids show by all the weird stuff that is happening there. It just gets more and more in a wrong direction and im very afraid of how extreme the episodes are gonna get in the future.
