The documentary is way more interesting than "The Devil Wears Prada". In fact, it focuses more on Vogue's art director Grace Coddington, than editor-in-chief Anna Wintour. The most interesting part (to me) is to see how Coddington works with photographers and how photos get retouched on fashion magazines. (A replacement for my failed attempt to go to photography school I guess.)
As for Wintour, she reminds me a very driven manager who really knows how to push her employees to go beyond their limits. This kind of boss you sometimes hate, but sometimes you are also grateful. The working dynamic between Wintour and her Vogue team actually reminds me situations in my current company.
P.S. looking at those fashion models doing cat walk, I suddenly had a vision of seeing real cats (all the cat families, including tigers, leopards, cheetahs, etc) doing it. Too bad we cannot herd cats. Otherwise that would be quite a sight. Even super models look pale compared to those real cats.
