the only reason Ren and Stimpy was any good was because:
A) the people below him had more talent than he did
B) the people above him disapproved of anything too terrible
on top of that, John K is just a terrible person to work with. almost everyone who works with him never wants to work with him again, look at Billy West or Katie Rice (the only person who has ever had anything nice to say about him is Mike Judge). He has terrible work ethic and constantly missed deadlines, which led him to be fired from Nick.
any time John K gets more creative control, the production turns to shit.
remember Adult Party Cartoon? It was terrible.
remember Super Ripping Friends? Yeah, me neither.
remember those terrible, terrible, terrible Simpsons couch gags he did? I try not to.
remember Cans Without Labels? nobody does because it hasnt come out yet.
John K. is a garbage hack and anyone who calls him an inspiration has no clue who they're actually inspired by
