I'm extremely not surprised given the terrible treatment of the show.
Firstly, let's all agree that Disney XD is all but a failure. They put these shows on a strange channel that you have to gert the super gold platinum premium ultra package to even see. That doomed quite a few third party cartoons on the network, especially Doraemon, and I think that's why Phase 5 (or whatever its called) put Yokai Watch on Netflix. That should have been a massive hit, but it's inaccessibility hampered that. For once we'd get a toy based anime that was actually popular in Japan. Disney should have been a lot more firm and put their foot down with cable providers that XD be as accessible and available as the Disney Channel. I think in essence, a girl's crapcom channel and a boy's cartoon and comics based channel were a brilliant idea. But it's one wasted with being lost on a premium package. I wouldn't be surprised if that was what also bit The Hub square on the butt.
I just found out I actually get Disney Jr. but still no XD.
And don't get me started on that hour long block on Disney Channel of XD shows. They've been wasting it the past 3 weeks on some awful prank show. Had their afternoons been cartoon reruns, maybe that would have perked up the ratings.
And secondly, the way the show was treated. It was clearly developed and meant for a Disney Junior release, and there's absolutely nothing objectionable in the series to disclude it from one. But for no reason whatsoever, this educational show that still had the educational bits in it wasn't deemed acceptible for the preschool line up. And thus, the show was too young for the XD crowd but somehow too old for the preschool line up. And I can't even get sore at that because it's not like their preschool programs were even remotely bad at the time. It's just...weird it wasn't included and didn't get the merchandising bonanza other preschool series got. Had it been included, I think it would have succeeded. But it wasn't and it fell into obscurity. I wouldn't doubt dropping it is part of the draconian "we gotta make those ingrate stockholders happy" movements this week.
