At the urging of several friends, I started watching the popular British sci-fi series DOCTOR WHO. Starting with the 2005 revival of the series, I've now watched it through season four, which saw the departure of David Tennant from the role of The Doctor to make way for yet another actor (the series actually incorporates the change of actors as the Doctor "regenerating" into a new body following a fatal injury). Well, I was so fond of Tennant's version of the Doctor (the "10th incarnation"), and so blown away by season four's finale, I thought I'd say "so long" to this version of everyone's favorite Time Lord in my own way.
