My Mum was a huge fan (mainly of Jamie, lol) so it was something we watched without fail whenever it was on, therefore I don't remember seeing it for the first time or remember not watching it as a child in the early 70's.
Tom Baker has been my doctor for a very long time, with JP and Davison a very close joint second. Much as I had enjoyed the reboot neither Eccleston or Tennant had any hopes of beating these three in particular, but since Matt Smith has taken on the role he has become my new favourite. 11 simply is a 900 year old alien which I don't feel 8-10 managed to consistently portray, thou I do enjoy them in the role
