I started watching the new Who because of Matt Smith, when I just happened to catch The Eleventh Hour when visiting a friend. I thoroughly enjoyed the episode, culminating in my giving a little gasp at the rooftop scene when Matt walked through the tenth doctor's image and announced, "Hello, I'm the Doctor".
Having fallen in love with the series I bought myself the box set of Nine and Ten. I adored Christopher Eccleston and enjoyed David Tennant (who I felt was occasionally a bit hammy, despite being a great actor).
Episode wise, Eleven gets my overall vote. As with any long series there are episodes I like more than others, but in the main I would agree with Raven's post. The Doctor's Wife rates as a favourite of mine that I felt had a great balance of humour ("It's like kissing, but there's a winner") and sentiment. The Girl Who Waited has caught me at each viewing, and even thinking of it makes my heart ache a little.
I think the Christmas episode this year was a tricky one after such a fab 50th Anniversary episode, and I only had one real qualm about it.
I'm looking forward to Peter Capaldi as the Doctor, and have no misgivings about how things will develop with him.
