These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Audience-Alienating Premise: Most of the things associated with the Rock Angelz movie and doll-line, the CD included some pretty great songs (Nobody's Girl and So Good) and the video game (also mentioned below).
Broken Aesop: The Bratz will often encourage people to be themselves...right after they give them a make-over, that is.
Creator's Pet: There is a reason the word Closmin exists. MGA's ability to create lines with only Cloe and Yasmin and if not create clones, nicknamed Closmin clones, who are Cloe and Yasmin in all but name.
Supposedly the preference for Yasmin is because the name and appearance of the doll is based on the creator's daughter.
Family-Unfriendly Aesop: The book Will Work For Fashion has Cloe getting a job to buy a dress she wants to wear to her first art gala. This is treated like the worst thing any teenager has ever done because she isn't spending every moment with her 'friends'.
The same book has Cloe (Working in a cosmetics shop) mix and match make up of different sorts without her boss' permission. When her boss finds out and fires her, he's treated as the villain.
If we speak of Bratz Rock Angelz, there's Jade saying that if someone was mean to you, don't get mad, just get back at them. And that's not all; they keep talking about how Burdine is going down and how much revenge they are going to commit against her. Sure, she was really mean to Jade at the beginning of the film, but she didn't deserve that much backlash. It makes the Bratz look like revenge-hungry Designated Heroes who refuse to be nice to their opponents (like most child-centered media encourage children to be) who didn't do anything really that criminal to begin with.
