Why won't Nicktoons air it on the US

I don't see why Nicktoons choose to air crap in US over this. I didn't think it was bad show it wasn't the greatest. I wouldn't say it was the greatest cartoon on the face of the planet earth but it is still an ok show. It was a fun show to watch for an half hour. When nothing else is on I would rather watch Mr. Bean: the Animated Series then CatDog, Chalkzone or Surkien School. I just don't see why Nicktoons US thinks its so bad I guess I never will. But anyways I rate Mr. Bean 10 stars.
