I am wondering perhaps if the focus of the press on the additional characters is less about whether they are going to have an impact on the show's dynamics, and more because the press are reacting to fans 'interest' in the new women.

Thoungh fan reaction has been largely negative (I don't include myself in this; I'm going to wait and see), it was still a significant reaction. An explosion even, in internet fandom terms ^_^ Thus, I reckon the media thinks we're intereted in knowing more, even if only to add to the ruckus.

You're not being sensitive though. I may be apathetic about the new additions, but I ALWAYS want to know more about the boys!
