More Dr Who

I don't want to keep going on and on about Dr Who, but....... I'm gonna:

I've just read on BBC News page that Katherine Tate is to become the Doctor's new assistant. WHAT! I am gutted. Martha Jones (Freema Agyeman) is a great character and I really didn't want her to leave and I really don't like Katherine Tate as an actor. I'm one of the few people who can't stand her "Nan" character. And she is going to be in the whole series!
Freema will be in 3 episodes of the next series of Torchwood, and will return half-way through the 4th series of Dr Who, but I am just so disappointed about Katherine Tate. Hopefully she will prove me wrong.

PLEASE Katherine, Prove Me Wrong!!
