Total Scifi have voted Doctor Who the best ever SciFi television show.
"There have been plenty of mind-bending, thought-provoking SF shows in the history of television, but none have proven as enduring as Doctor Who.
The key to the show’s longevity has been its ability to re-invent itself for new generations while maintaining a consistency in tone and character, and the Daleks and TARDIS have now become part of our cultural landscape.
