Why haven't I watched Invader Zim before, ITS AWESOME

I just got done watching the whole 2 seasons of the show and the movie that came out in 2019 and I seriously wished I could've grown up watching Invader Zim. The type of humor and the art style grabbed so much of my attention. I was honestly surprised it was a Nick show as it kind of gave me more Cartoon Network vibes. I was mostly a CN kid growing up so I rarely watched any Nick shows and when I did it was mostly SpongeBob (o3o). Still I'm gad I gave it a chance to watch and I can say I'm a Fan of it now X3. 

Any shows you guys recommended that is similar or even something different to watch? 

(I love GIR, He is me :P)
