The four heroines are multi-cultural and (mostly) confident in their abilities and friendships. Furthermore, they dare to socialize with people outside their clique at school, and one even urges her divorced parents to be civil to each other. There's a big qualifier though -- as befits characters based on a product toy line -- that they're fixated on fashion and material possessions (Buy! Buy! Buy!). Some stereotyping: the Asian-descended one is a science-math whiz. A boyfriend character is deaf, but defies the disability.
Some slapstick pratfalls, food fights, and a hostile athlete gets martial-arts punched (and impressed) by a science student.
A few provocative or tight dresses on the girls, and bikinis at poolside.
Not only are the main characters inspired by a line of toys, they're surrounded by (and practically engulfed in) brand-name clothing, cars, computers (Apple, of course), and a shopping-as-empowerment message.
