I've liked a lot of entertainment aimed at young people. Harry Potter, Mystery Train, all sorts of things. So when I say Naomi seems like a show for mid teens, that doesn't mean it inherently couldn't have been entertaining for adults.
But in this case the series feels very focused on a target audience to the exclusion of everyone else. It just feels like a kid's show. And that makes it hard to rate.
However I can say that the first episode moved very slowly and the dialogue was very cliched and corny. I just can't see watching more of it.
