Okay, the eyeball-ripping, disturbing character designs and references to stuff kids shouldn't see (a clockwork orange, end of evangelion) might have something to do with it. Annoying target audience.
Yea, I was always confused as to why Nickolodeon OK'd Invader Zim. Did they just not notice JTHM or something?

Invader Zim got "canceled" because he accidentally rampaged through Nickelodeon studios, thinking it was PBS Networks' studio.
