I enjoy a lot of John K.'s work. The original Ren & Stimpy, Ripping Friends, Ren Seeks Help, some music videos he's done. He knows his shit about animation, and has a fun, dynamic, fluid animation style. His style greatly influenced me as an artist, and try to follow a lot of his teachings about organic shapes and dynamic cartooning. Not because he says so, but because I agree with them.
That said, however, the man is an arrogant asshole. He takes his opinions to insane extremes. He hates anything modern, Japanese, or made by Disney. I mean, sure, Japan and Disney make a lot of garbage, but John doesn't give things like Lilo & Stitch, FLCL, Dead Leaves, Gurren Laggan, Akira, Pixar movies, and so on a fair shake, which is bullshit. There is lots of good modern/Japanese animation, and he snubs all of it.
Yet he praises the likes of old shitty Hanna-Barbera cartoons and 50s cereal ads. He contradicts himself all the time. Half the arguments he makes don't make any sense. When he does make a good point, he takes it too far. He lusts after the young, female artists he hires. He's just a douchebag.
If he just compromised A LITTLE and became even SLIGHTLY more open to modern trends, he could make awesome, successful cartoons. But I guess he enjoys not getting work.
But he certainly doesn't suck. Shame on anyone who said that. He's an asshole, but a TALENTED asshole. Well, when he's not making shitty Flash cartoons, that is.
