Sorry if you're not a fan, but I can't help myself

Smith is a fan of Troughton, and he dances around the crotchety-loveable-mad axis from the off. Smith's age also turns out .... to be something of a non-issue. Moffat's line is that although the Doctor uses 900 as his stage-age, he can't have any idea how old he is: he's a Timelord, these things are wibbly-wobbly. And Smith carries off the youthful vigour of a new body and the ancient professorial wisdom with easy panache. The much-heralded 'recklessness' is there as well...
