I've seen it in bits and pieces on Cartoon Network a while back. It's not too bad from what I've seen.
I had as well, so I thought I'd had a line on it.
Once again, subbed and in order makes all the difference.
My preconception was that the artwork was primitive from the TV fare.
I'd say what really happened is that it's focused visually just on the essentials.
That came crashing home when I was interrupted and it felt like being interrupted from a book - as I glanced at the paused screen upon returning, I realized that a lot of the visual definition was in my imagination.
Plus, I love the intro tune.
