Invader Zim was and still will be an awesome show. It is a shame that they cancelled it. Did the parents think it was too violent If they did think it was too violent, there are other ways then just to cancelled it. Why not move the time to 10:00-11:00 pm Did Nickelodeon not approve of it anymore Well if Nickelodeon wont approve it why not put it on different channel The point is, they should put it back on the air. If you love Invader Zim as much as we do, then please, sign up now to try and get it back on the air.
