I have loved it since I used to watch it on PBS and TVOntatio. I love the reboot, and I like all of the actors who have played the Doctor since the reboot for different reasons. Matt Smith makes me think of that cool, albeit sometimes arrogant, older brother who went to university, then travelled the world & has come back home to take you and show you all he has learned (sort of like an alien Auntie Mame) I'm actually impressed with myself that I figured out who River Song was before the episode revealing who she really was aired (a very clever twist indeed!)
Of course I was a fan of the Jon Pertwee era with Jo Grant & later Sarah-Jane Smith, but THE classic Doctor Who combo was Tom Baker as the Doctor with Liz Sladen as Sarah-Jane Smith. I was heartbroken when Liz Sladen died of cancer this past April. Having grown up with the character and enjoying her again in her resurgence since the season 2 episode "School Reunion", I felt as though a part of my childhood was stolen from me. Sounds silly to say about someone I never actually knew, but I guess that's a credit to her acting & her charisma.
I watched Peter Davidson, but Baker was too much of an act to follow, and I never warmed to Colin Baker or Sylvester McCoy.
