There's a new animated Cat in the Hat show on PBS. The animation looks awful to me, but it took me a while to figure out why. The 2d animation uses no motion blur at all, making it look like cheap Flash animation. Super Why uses 2d animation for its book segments, but it uses stylized art and motion blur to make it look pretty good. And the animation in Caillou looks cheap, but it's minimalistic and slightly charming. The animation in Cat has fancy drawings but awful animation.
It doesn't help that the Cat himself is voiced by Martin Short in bellowing over-the-top mode.
(These are the things I think about as the kids watch this stuff, loving every minute of it. If only they knew how awful it was!)
