I was acquainted with Zim through PPGD. A few years after I exited that life, I watched the whole series (including the movie) over a summer. Laughed, cringed, had a lot of fun. ^^ Fast forward to now, where I look at the comic every once in a while, and wear my Zim snapback all around college (it's basically my 'cool hat'). I'm just a casual fan, though.
I haven't seen or read any info on the new thing...but what do you mean, 'art style'?! Is there a new art style?! What was wrong with the old one?!
