I saw the leaked preview episode, and all I can say is this.
I can expect no less from former Animaniacs writers and producers, and it blew away my already high expectations. In other words, I thought it would be good, but didn't think it would be even better. But the biggest surprise was Kelly Osborne. She's... good. She's very good as the show's villain. I didn't even realism it was her until I read the credits.
Other than that, I read this was supposed to be a Playhouse Disney show, and it does have some younger audience elements to it. They read the titles aloud for example. I guess they decided it was a little intense or something, and that's a shame, since it goes to prove that their Playhouse shows are getting good by doing their own thing and not just ruthlessly copying Dora. I caught some of Sophia the First, and it was GASP!!! watchable!
