With David it's his intelligence that makes him sexy. Obviously he's a good looking boy and in good shape, but fundamentally it's his intelligence, he is curious and full of ideas. He is also rock solid Labour, which is always a plus.How could that conceivably be a "plus" in relation to his acting or general suitability to portray a Time Lord from Gallifrey? I am a huge fan of Dr Who. I consider the Tardis to be the cleverest construct in the whole of science fiction and love the humour of the show compared to the po-faced, up-themselves worthiness of other great sci-fi franchises. But it's hard not to notice than any business-person who makes an appearance is seeking to profit from the sufferings of others or to destroy a planet in order to revenge himself on the board that fired him.
