Code Geass.
Oh, Code Geass is some kind of art alright... There's got to be some merit involved in creating something that infuriating yet somehow watchable...
Or so you'd like to think. Still, character designs are by CLAMP, and they are undoubtedly artists, and I would argue they're good ones (not for Code Geass, mind, but Clover, X, Cardcaptor Sakura manga are all quality) so I guess it qualifies.
EDIT:
Art quality. Not touching plot, so set down the torches. (though in the 3 I mentioned, I wouldn't think there'd be much objectionable about the plot either, as long as you consider that other shows you might think are using that stale old plotline are ripoffs
of X. Anyway. God, I'm equivocal.)
