I have every faith in Jeff, he seems to really enjoy it - something I wasn't convinced of, with Des squared! He's relaxed and easygoing, and gets the humour just right imo. Heck even my 85 year old MIL, who had no idea who he was, has taken to him. Took Rachel longer, but she's finally settled in and mostly gets the numbers now. Personally find it a very watchable 40 minutes.
I bet Rachel's pleased her dresses are having the desired effect. She started off in fairly mumsy dresses, but apparently wanted her own style. So had a bit of a splurge on new dresses for the show; might be wrong, but I think her pink number today was the first one she's worn twice!
