QUESTION!

I'm thinking about getting started with Doctor Who, but I'm confused as to where to start. I've only watched like... 2 episodes before. One was one of the way earlier ones I think, this was years ago and I remember thinking it felt very ameatuer-ish. But then the other episode I watched was Blink, and I thought that was just fantastic. But I never gave Doctor Who another chance since I assumed that Blink was just a special episode and one of the reasons I loved it so much was being I think Carey Mulligan is one of the best actresses to come around in years. I love her.

And there's so many different doctors and whatnot. Not sure which one to begin with? Do I need to watch it all the way from the beginning?
