All good doctors come to an end. I wish Doctor Donna would have been a spin-off.

tom baker, use to be my favorite when i was a kid...then came david tennant, and he became my ultimate favorite.
matt smith, has big shoes to fill.

I really liked David Tennant as Dr. Who. I hope the new guy does as well. I hope that they get a good sidekick... Donna Nobel stunk.

[Doctor Who]

I couldn't stand Catherine Tate/Donna Noble either.

[a companion too]

i can't believe sarah jane's still around and has her own spin off show too....some folks i guess can't break from doctor who.
