I saw the first disc of this back when it came out. It's a quirky little series about a ditzy girl who wants to become an angel. At first I was a bit turned off by the animation style and the main character Noelle (heck, she still annoys me at times). But there's something about the show that I find myself enjoying a lot. The first bit that hooked me was a story that had more to do with Sarah, Noelle's sister. She's invisible.
I'm at episode 19 right now, so I'm not sure how everything turns out. But there was a wonderful storyline right around episode 12/13. And so far the show has one of my favorite lines ever: "Forgive me! The naughty me is a vacuum cleaner!"
