Alexandra S was right about the cover, the flag one wasn't as attractive.
She may not be high fashion like Paris and NY editors, but it's probably her ability to be the one that steers to the right commercial decisions that means she's good as the editor.
The others, the blonde, were egged on by the dipsy commentator. Why don't you say something, do you ever stand up for what you think etc. She felt that by not speaking up she wasn't backing her work and then it will fall flat in a room with the publishers.
It was a great doco, not flashy but really showed the tensions in a creative place where it's all about opinions - which in this case can be backed up by sales.
