Bad is bad, my friend, whether it's bad board-driven writing or bad script-driven writing. But I like how you say "one of the few places where John K. is absolutely correct," as though you disagree with him elsewhere.
Of course, If you do disagree with him, it could be because you're a Cal Arts graduate and he loves to piss all over that school. In other words: "When he dumps on you, he's right. When he dumps on me, he's a dick."
Two points on this, if I may:
1) I don't know what position you've had to "correct edit jughead's" scripts (I don't even know where to start trying to correct and/or edit that) but was it your job to do so? On a script driven show? Then, thank you. Because we're all on the same team here.
2) And of course the majority of WGA writers working in animation freely admit they would love to be writing films or other projects. They are paid more. And get residuals. And a better pension. You gonna tell me an animator wouldn't step over the face of a basic cable executive to get a shot at a feature film? Of course he or she would.
I love the math here. "A few artists" who can write just as well than the entirety of the WGA. I'm sure there are. Emphasis on "few," just as I'm sure there are a few WGA writers who can draw better than some artists. Writing is art, just as drawing is art, just as timing is art, and editing is art, in its own way.
I'm sorry you can't respect anything that you can't or won't do, but that's your bag of cats, not ours. And finally:
