"I love humans... always seeing patterns
in things that aren't there."
Although
I'd seen the odd (in more ways than one!) Doctor Who episode
while growing up (and laughted at its infamous not-so-special effects),
I didn't become a fan until 1996 when I saw the Fox TV movie. Naturally
then, Paul McGann's 8th Doctor is my favorite.
Of the rest of the Doctors, Tom Baker's 4th Doctor is my second-favorite
and the 5th and 7th Doctors (played by Peter Davison and Sylvester
McCoy respectively) are tied for third.
While I haven't seen every Doctor Who episode, I have seen
most of the "famous" stories and I devour the novels I
think in general, they're the best-written media-based SF out there.
