.... And Don't Blink!
I have to wonder whether the author of this article also bitches that nobody's writing stories like those from the Golden Age of SF between the 1930s and the 1950s any more.
Well, oddly, Doctor Who, like all other Sci-Fi, grows and changes according to the times it's in. So much SF is a reflection of the social conditions in which it is written (compare the Cyberpunk of the 1980s with Banks' Culture stories for example)
Each Doctor is different, to expect them to all be the same would be to put the series into a strait-jacket churning out the same old stuff over and over again which would be tedious beyond belief.
Instead we have developing characters and story arcs (including the wonderful "backwards arc" of River Song) and still the Silence one continues. If that's not your thing, please feel free to go back to the three R's of Rockets, Rayguns and Robots, but let those of us who appreciate a bit more subtlety on their SF enjoy what is a great series *now*.
