I'm shocked and appalled that there wasn't already a Doctor Who thread here!
Favorite Doctor: Sylvester McCoy (Seventh)
Favorite companion: Dorothy "Ace" McShane
Favorite villain: The Master (especially the original, portrayed by Roger Delgado)
Favorite Classic Who story: Remembrance of the Daleks
Favorite New Who episodes: It's a tie between The Doctor Dances and Heaven Sent
Favorite regeneration: Christopher Eccleston (Ninth) to David Tennant (Tenth)
Hopes for the Thirteenth Doctor: Idris Elba, Tim Roth, or Hayley Atwell
