He's no dancer, is he? He should get himself out of SCD as quickly as possible and sneak off to mine for a night of comfort and consolation and then we can practice the tango naked (although I'd rather roll around the sheets with him

)
Actually, I've just gone on That Site and watched the dance (which I managed to blink and miss tonight

) and it wasn't that bad.
What the Op says about no smile - well it's the Tango, you're not actually supposed to smile when you're doing it, it's not that kind of dance.
Regarding his bottom, well my computer screen probably needs cleaning and I haven't loaded my video drivers since reinstalling all my stuff after an HD reformat two weeks ago, but I thought some of that was just his suit. He was nowhere near as bad as he had been rehearsals, although the judges did pick up on it and I agree there was some of that, but not as bad as some on here are saying.
Just my opinion. I'm sticking up for the Castle here (oh, and a note to Mrs Castle, I was only joking about the naked Tango thing

)
