Ok. Confession. I haven't missed a single episode of this new series of Dr Who. David Tennant is very much in keeping with previous Doctors in his geekiness and nerdiness. I can't remember all the Doctors, but the ones I do, I don't think any of them were as sexy as Christopher Ecclestone. Therefore, I am forced to conclude that David Tennant is a good choice, and Ecclestone was the aberration.
