Actually it's quite funny - A friend of mine had recommended Dr. Who a long time ago, but I only recently got into the series when I started watching it on Netflix. I have to say that I truly enjoy this show, it has such a good mix of comedy, action, and drama - and it all fits within a 50 minute episode.
I've finished all of Christopher Eccleston's season, and am now working on the first season with David Tennant.
Also, it was really funny because at a recent anime, gaming, and sci-fi convention that I had gone to earlier this summer, we were playing cosplay chess (people dressed up as characters fill in for the chess pieces while two people play the actual game up on a stage) and one of the players moved his piece to take another. Well the person who was representing that piece down on the floor was a Dr. Who cosplayer (who could have been David Tennant's brother) and when he went to kill his opponent he told them "Look, I don't want to have to kill you, can't we reach a peaceful settlement?"
