Doctor Who is not only my favorite TV show, but one of my favorite things ever. I have adored it ever since I watched the Peter Cushing Dalek films. I adore both the classic and new series equally, and I think it is a shame that Matt Smith is leaving as the 11th Doctor. It for the best in the end though, I mean, for 50th years the show has been about change. Cant wait for the 50th special!
Also have to mention how much I love Torchwood, its adult-centered spin-off (And where I got my username from!) and The Sarah Jane Adventures, its more child-centered spin-off.
