Between the CG and the script, I just feel like it was way to rushed compared to the other Barbie shows. Not only has it been done many times before, but it's not even done that well. I get that they are trying to bring the idea of Barbie as a teenage girl in high school but they pretty much made diaries of a teenage drama queen in CG. All in all, pretty lame but not the worst. The writing lacks heart and is corny a lot of the time, the story is shallow and predictable, I didn't like the messages of vanity and obsessing about being popular and boys and the characters while not as bratty as Fairy Secret and Fashion Fairytale are not very likable and are very stereotypical.
However, the animation is not as vibrant or as detailed and at times even looks rough. The soundtrack was great, the ending with Barbie redeeming herself was nice and the voice acting was good, unlike the two I just mentioned Barbie Diaries actually has the advantage of Barbie being voiced by Kelly Sheridan. It is better than Fairy Secret and Fashion Fairytale, unlike those two while lame it isn't completely awful. I say this as a 20 year old female who actually does like the Barbie movies, especially Nutcracker, Diamond Castle, Prince and the Pauper and Island Princess, Rapunzel, 12 Dancing Princesses and Swan Lake I also have a soft spot for.
