I personally have no interest in it, but I think it's great that it exists for little girls to have a superhero cartoon of their own that isn't just Powerpuff Girls or some other off-shoot of female superheroes like Super Best Friends Forever, which always seemed fun but wasn't really pushed by Cartoon Network. 

Sometimes it's just good for stuff to exist for target demographics beyond yourself, because without some of the media that catered to kids whenever we were that age, we probably wouldn't be there. I'm vehemently opposed to the idea that comics and comics media always has to be for us or, more specifically, our generation.
