Not for me, she comes over as sappy and even more irrelevant than the rest of them. It would have been so much more refreshing to see somebody with a bit of personality, she just bores me.
If she manages to annoy people by not having opinions, imagine how many she'd annoy by speaking about them.
I think when it comes to the royals, the women are always judged more harshly, and those who marry in even more so. The media will either hold them as the darlings of the nation or go for the throat, and sometimes both in the same week.
If Kate and William show up at the same event, say and do the same things, and each wear suitably appropriate outfits, you'll see Kate's outfit picked apart and her actions questioned, while William might get a brief comment.
In her position, the safest option is to be seen as boring. Boring is harder to talk about.
