Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.

Forgettable.

I think the premise of this show largely killed it. The main characters are at the center of the earth and you have the good old rule of three at work, but I think at some point they realized they didn't have enough to answer the question of why the viewer should care. Interaction would largely have to be removed in a setting like this and there's only so much you can do with three characters. An effort was made to remedy this and as a result you get a host of wacky, random characters that pop up out of nowhere. There's no explanation of how they have survived Earth's molten temperatures (Especially the Plant Girl, Judy) No explanation for why they speak perfect English, No origin stories and no consistency. What really makes me believe that they were just winging it was the ending. It ends with Billy and his hosts of friends being attacked by aliens and fighting to save Subterrainiatania. Ok. So everyone ON earth didn't notice their planet being attacked or approached and only the people IN Earth know about it? How does that make any sense? What's worse is that the leader of the Aliens is a doppelganger of Billy ......that turns out to be a robot.... that turns out to be a giant larvae that vomits all over itself and dies before turning into flowers. Do we ever get ANY kind of explanation as to why this is? No. Not a hint. Not a clue. If you do decide to watch this show be prepared for a forgettable mass of loose ends with no explanations for anything, no well-rounded characters and no educational value. It's about as bare-bones as you can get when it comes to creating a Cartoon. I have to wonder if they just stuck an unfinished product on TV and thought we wouldn't notice.

NOT GOOD

I hate it it' always messes up other programs for my child and she cries when this ABOMINATION comes on the screen and it's super annoying Billy Dilleys voice is so high pitched. I feel like Disney channel now focuses on being idiotic because of its "younger viewers" but this show is plain out stupid and it shouldn't have been made in the first place. And if the creator of this so called "show" is reading this then you should take it down for the people's sake's
