It was great to see this style again! Well anyway, there actually is in fact a comic book continuation of the "Invader Zim" series, so it isn't gone forever. Oh, and they apparently aired all the episodes later. Well, I didn't quite follow it after that. The animation is spot on. I do think the voices could be a little better.
I especially didn't care for Dib's. Still, this does seem like something that would occur in an episode of the show. I wish it was a full episode! You guys certainly have potential. No, it wasn't horrible.
