Eh, impressive, but only in relation to what seems like a whole new generation of shitty cartoons to a 90's kid. Show is undeniable quality, but not to any degree that justifies this apparent infatuation among grown men. Powerpuff Girls this is not. Whole thing still seems a bit queer to me, but who am I to judge?
I was born on the 83, thus I growed up watching mostly 80's and 90's cartoons. Present-day cartoons shits all over the pieces of crap that I used to watch when I was a kid, Jesus. I even tried to re - watch some of the older episodes of the series that I used to like, and not even nostalgia can save them. We are truthly in a golden age of TV shows and series (animated and non animated alike), and by golly, does it shows or what.
