Query: Barbie, A Disappointing Movie

This was the first Barbie movie my family watched. My 5 year old has been begging to watch it for weeks.This is one of the worst children's movies I've seen in some time. The theme -- mean-girl boyfriend jealousy -- is inappropriate for young children. The characters are too obsessed with fashion. It's the 21st century; surely it is time to move away from the stereotype that shopping is the only thing on young women's minds. The writing and plot are insipid("Gloss Angeles?") and the quality of the animation is poor. We've not seen the other movies, but I've read two of the books to my daughter; they were equally awful. Mattel is ruining their Barbie franchise with these poor-quality products.Disney did a fantastic job with fairies; both the movies and the books are excellent. I've not seen the My Little Pony movies, but the books are readable and age-appropriate. Disney and Hasbro can produce high quality stories to accompany their product lines. Why can't Mattel?
