I always used to like her and I thought the reason she didn't go into much detail was because she's doing what she's been told to do and she only has a short amount of time for each dance.
But when Chloe and Neil were on it, they made loads of really interesting points and I realised how much better it could be.
I don't dislike Karen but maybe she's going a bit like Craig and Bruno, sometimes more interested in creating an image than doing her job?
