I never got into “Ren and Stimpy”. It was my kind of humor (in parts), it was targeted at my demographic, even, but…it was ugly. I don’t mean content-wise, which was a combination of juvenille and surreal, but the actual graphics were.
But I blame it for the rash of ugly cartoons that have persisted to this day. Many use similar techniques that John K. pioneered (not all of them unaesthetically).
I shouldn’t say “blame”, since I just don’t watch shows like that. There’s a new one called “The Misadventures of Flapjack” which reminds very strongly of R&S.
I’m not sure where the line is or when I drew it. I love, for example, “Duckman”, though that’s right on the ragged edge. I watched the crudely drawn “Home Movies” faithfully, the Hanna-Barbera styled “Sealab 2021”, and I can even endure “Aqua Teen Hunger Force”. (Except for “Duckman”, these are all Adult Swim programs.)
Meanwhile, I can’t watch “Tom Goes to the Mayor” or “Tim and Eric Awesome Show Great Job!”, even though there are a lot of names I like associated with it. Same with “Metalocalypse”.
I used to watch Adult Swim pretty faithfully, but it’s to the point where 80% of the shows are just ugly.
