Not only the ratings were poor, but Nick started to lose interest once they found out about Jhonen Vasquez's other works, then Nick grew against it after the 9/11/2001 terrorist attacks in New York City, and finally, Nick cancelled the show leaving 7 episodes unaired (until 2006). Another reason was probably cuz parents found the show too dark and scary for young children.
