people may bitch and moan about Donna Noble, but at least I didn't find her as punchably smug as River Song.
On the contrary, I think that Donna was the best companion the new series has served up so far. A lot of that credit, I think, belongs to Catherine Tate. As such a talented, experienced comedianne, she was the only would who could meet David Tennant on equal footing and just let their performances bounce off each other. It was beautiful music together. (BTW, I'm a huge fan of
The Catherine Tate Show and I recommend it to everyone here.)
