Doctor Who ... all of it... I find, ages really well. Some, however, age much better than others. While I find NuWho to be good at pacing... ClassicWho is better for far more rememberable stories.
My best friend and I have watched Doctors 8-10... and we're currently half way through series 4. He thought he'd never like David Tennant.
David Tennant is now his favorite Doctor, so far, and has almost completely forgotten about Eccelston. (No, not literally) but he forgot that he once told me he'd quit if David was terrible. XD
It's funny seeing him react to pics of Matt Smith. He sort of sounds like the summary of all the worried masses of the Doctor Who fans
He's too young! Look at that hair!? What the crap is he wearing? Blah blah blah...
I know he'll love 'em. XD
