I seem to remember Len's head-judge casting-vote face including a rueful eyebrow raise as well. I don't mind Shirley's face but Len's was better.
I think it was interesting that Craig openly defied the DO rule by saying he was saving the better dancer, not the dancer who did better in that specific routine. I do think DJJ had further to go than Graeme, who has definitely reached his peak and is now just the comedy contestant.
Re DJJ thanking the singers and musicians, I'm sure others quite often thank them too. And re the mini interviews, my TV recording cut off before the end of the show so I didn't see the broadcast ones, but I watched a clip of it on Twitter, posted by the Strictly account, with a few of the other couples saying positive things about him. One of them was Charles saying he was sad that his bromance had gone. I wonder if the Beeb deliberately edited the broadcast version to give a different impression?
Overall, I'm pissed off DJJ has gone. I'd far rather watch him than any more comedy/galumphing Graeme routines, much as I like Oti.
