Who else didn't like (The Grand) Sophy?

[Jiji]

Anybody else DID NOT like Sophy? While Charles's fiancee is called a busybody, why isn't Sophy? She does much worse and against the conventions of her time. Would she really have been accepted with all her antics in that time? Everybody comments on Charles being quite dull: what would you have done with 7 brothers and sisters, a weak mother and a gambling father? And he's (IMO) quite accepting of Sophy's antics (I mean we are talking regency period not 2000s!). I found Sophy particularly annoying the way she always seems to think she knows everything so well. And for a heroine,she is quite nasty ('horse face' comment; anyone remembers?)
