I know there are COUNTLESS series and spin-offs.
The one I discovered and am watching right now is the 2005 version - present.
I am now watching the "Tenth" Doctor
Just finished the "Daleks vs Cybermen" episode. (WARNING: SPOILERS)
Not too sure what this is all about but I'm LOVING this Sci-fi stuff.

I'm not kidding you, this is the FIRST time I ever HEARD of "Doctor Who".
I only learned about it from Futurama.

Because of the Doctor's ability of regeneration and the parallel universe theory explanation, a few 'interesting' spin-offs have been made by fans.
Different Who(s) fighting different battles across the universe(s)!
HOLY CRAP
A Doctor Who Anime!
This stars the "Third" doctor. Older, but a much better fighter than the rest of them.

AHaha - a MLP and Doctor Who spin-off
"Allons-y" is French for "Let's GO!"

I am dead serious, I had NO idea what Doctor Who was about.
I never even heard of the name until a friend pointed it out in a Futurama episode.
