Without getting into the socio-feminist merits of a Barbie collection, I
will say that the prospect of getting some great Barbie pink lipsticks is A+++++.
As for Bratz dolls, I can't see any positives in a range of dolls that promote ethnic stereotypes (a sociological paper I read recently made mention of the dolls being directly modelled on the twin stereotypes of Latina 'hoochies' and African-American video girls), where the hottest accessory is a tanning bed for the Baby Bratz line (I can't even begin to tell you what's wrong with that) and, as insignificant as it sounds, came with little g-strings/thongs in their boxed outfits. This is all for a line that's marketed to the 4-10 year-old market, remember.
It might be trite and a bit hackneyed, but it still remains that for all her negatives, Barbie at least did something. For all her shopping accessory packs, make-over parties and beach house kits, she was also a student, a doctor, a teacher, an astronaut... Mattel imbued Barbie with aspirations beyond shopping and Ken.
But really, it's all about the bright, bright lipsticks.
