When I was younger I couldn't get into Doctor Who--I knew some people really into it, but when I saw it, it just didn't' do anything for me--maybe it was the style of narrative, the serial nature of the stories or something like that.
I loved a lot of British shows--so it wasn't that.
The cheesy sets & costumes didn't turn me off (I've watched & enjoyed other shows & movies that were at least as cheesy)
then when the new version cam along some other people I know got me into it--and it was fun.
I still prefer the newer version to the older version, but have a better appreciation for the older version, as I saw some episodes I had never seen before (And some of the Doctors I hadn't seen before.
The poll closed before I could vote in it, but my favorite is Eccleston.
he brought an edge to the role with a sense of humour that fit well.
I loved his line in the two parter to end his time on the show-after saying "No" to the Daleks sveral times-he tells the Daleks he is going to rescue Rose, save the earth and wipe them out of the sky.
When they tell him he has no weapons, no defences & no plan he responds-
"Yeah, and doesn't that scare you to death"
And them seem to show fear.
Cool.
Go to about 2:00 if you want to skip ahead (& about 2:53 for the line quoted):
My favorite of the "classic" doctors is Jon Pertwee--he had a cool vibe to him.
