Truly, my wife will miss David Tennant.  I never imagined her becoming a Doctor Who fan, but Tennant pulled her in and kept her there long enough for her to get hooked.

But he is bowing out, soon to be replaced by Matt Smith.  If you’ve not heard of Matt Smith, no worries, looks like he hasn’t done much TV work just yet, though he does have a bit of a stage career.  Coincidentally, he appeared on Secret Diary of a Call Girl.  Perhaps an encounter with Billie Piper led him to helm the TARDIS.

Knowing nothing of his work, I can’t speculate on how he’ll be as the Doctor.  Guess we’ll find out in 2010.

We are getting closer to seeing how they’re going to get around the 12 regenerations limit, though circumventing it seems a mere plot point.
